We Do Not Allow Suggestion or Suggestibility to Influence our Lab Results. – A Blog by Dr. M.A. Persinger

We take every measure to ensure that our subjects are not exposed to suggestions.

Our laboratory results are not due to suggestion or suggestibility – A blog by Dr. Michael A. Persinger.

We apply several procedures to guarantee that our subjects are not exposed to suggestions, have no expectations, so that our results are not influenced by subject suggestibility.

These procedures and analytical methods rule out suggestion as an explanation for the effects we have observed in our experiments.

Question: How do you ensure that subjects are not inadvertently given suggestions as to the purpose of your experiments and how do you respond to the claim that your results are due to suggestibility?

Answer: Human beings are remarkably sensitive to subtle cues in their environment. For example, specific areas of the human brain respond to alterations in structures of sentences while a person is reading even though the person is not “aware” of the change in sentence structure (Bern, 1997).

Thirty years ago when we were interested in the “subjective narrative” of people sitting in the dark in a quiet chamber we found that the music, e.g., a Gregorian chant or the bars from the movie Close Encounters of the Third Kind, compared to sitting in silence, affected the content of the “spontaneous” themes.  Sitting in silent darkness without previously hearing any music generated more “death” images, the pre-darkness listening to Gregorian chants was associated with more religious images and the movie score was associated with space themes.  We could influence what the subjects thought about by “priming” them with music with clear connotations.

Context is also important (Persinger, 1989; 1992). In a placebo-controlled experiment, we applied our magnetic signals, and immediately afterwards, the subjects listened to an ambiguous narrative (story) about a young boy who had night time anomalous experiences (“The Billy Story”) .  These were epileptic in origin, although this was never stated.  After the story and the stimulation was complete, we asked to subjects to listen to a brief story about either alien abduction or early sexual abuse.  The story was provided without any explanation.  The subjects were then asked to interpret the story about the boy’s night time experiences both immediately and a few days after.  We found that the subjects who heard the story about early sexual abuse interpreted the “Billy” story as one of sexual abuse, and the subjects who heard the story about alien abductions interpreted it as being about an interaction with aliens.   (Dittburner and Persinger, 1993; O’Gorman and Persinger, 1998). In this way, we verified how easily pseudomemories or false memories can be produced (Persinger, 1992; Healey and Persinger, 2001).

My critics who attribute God Helmet experiences to suggestibility have never directly tested this hypothesis. We have tested this potential confounding effect by psychometric inferences which are highly correlated with hypnotizability, such as the Wilson-Barber Imaginings Scale. We also have several experiments where we measured hypnotizibility directly with the Spiegel and Spiegel scale where the experimenter interacts with the subject directly (Ross and Persinger, 1987). The latter was administered after the exit questionnaire containing 20 questions about their experiences.

Interestingly, the last item in this questionnaire asks if the red light changed intensity even though for most studies there was no red light. Suggestible or highly hypnotizable individuals frequently respond “yes” to this item. However, even when the many suggestibility measures were taken into account during the statistical analyses, the sensed presence reports still occurred primarily when the “God Experience” protocol (Persinger, 2001) was used.

Dr. Linda St-Pierre and I explained this in our 2006 paper in the International Journal of Neuroscience, but online skeptics seem not to have read it.   Finally I reiterate that the volunteers do not know if they will receive a magnetic field or which field it might be and they are always told they are participating in a relaxation study.

We use questionnaires with our student subjects.  The questionnaires are applied at least six weeks before these students participate, and these are only some of the questionnaires they students fill out as they study psychological data gathering.  This gives them first hand experience with methods of gathering psychological data.  They have no idea that the questions have anything to do with the experiment.  The data is gathered under “blind” conditions.

We do not decorate our lab with any spiritual or religious imagery, and the researchers don’t discuss the specifics of the experiment with subjects until after all data have been gathered.

One experiment made it clear that our effects were not coming from suggestion.  After experimenting for several years with a burst-firing pattern, and seeing repeated results telling us that it generated higher pleasantness ratings when applied over the left hemisphere (see example; Persinger & Healey, 2002), we began to investigate another signal (derived from hippocampal tissues during long-term potentiation).  In that case, and in a few since, we have seen that this signal is more pleasant over the right hemisphere (Persinger, et al., 1994).  If our effects were due to suggestion, these results should have been the same in all cases, but they weren’t.  We’ve also had many other results (for example, with lab rats) that simply cannot be explained by suggestion or suggestibility.

I hope this blog clarifies that we are aware of experimental factors that allow suggestions and suggestibility to confound experimental results, and that we take all necessary steps to prevent their occurrence.

Our results can’t be attributed to suggestion. – A blog By Dr. Michael Persinger

Shiva_God_HelmetThe results of our experiments using complex magnetic stimulation cannot be attributed to experimenter suggestion or subject suggestibility. – A Blog by Dr. Michael Persinger.

Question: What results have you had that cannot be explained by suggestion?

Answer: We have seen many effects from our complex signals that cannot be explained by suggestion or suggestibility.  Some of them have been done with people, rats, worms and living cells maintained (cultured) in petri dishes, and you can’t influence living cells (in vitrio) through suggestion.

One very clear illustration is seen in our study that found that our magnetic field stimulation actually enhanced hypnotizability (Tiller, 1994) with a pulsed field, which we replicated two years later (Healey, 1996) with a burst-firing pattern.    We took measures of the suggestibility of each subject using an established instrument for its measurement as part of these experiments (Spiegel, 1978).  Altering suggestibility through suggestion is a highly improbable scenario, so the results of these studies ruled it out as an explanation for our magnetic stimulation effects in humans approximately twenty years ago.

For many of our experiments that created the sensed presence, we measured suggestibility directly using a well-established protocol (Spiegel, 1978).  We found that analyzing the data for the person’s hypnotizability score did not reduce the intensity of the sensed presence produced by the specific magnetic field pattern. The key paper was called “Experimental facilitation of the sensed presence is predicted by specific patterns of applied magnetic fields not by suggestibility: re-analysis of 19 experiments”. It was published in the International Journal of Neuroscience (St-Pierre, LS, 2006).

We have observed clinical effects that cannot be explained by suggestion. For example, Baker-Price (1996) found differential changes in the EEG patterns of patients who had sustained head injuries, depending upon the specific neural location where the field was applied.  The experiment also found a significant improvement of depression and a reduction of phobias.  We did a replication and electroencephalographic validation of this experiment in 2003 (Baker-Price, 2003), with very similar results and follow-up six weeks after the experiment was completed.  Tsang et. al. (2009) showed clearly with relatively crude psychometric measurements that infer emotional profiles that different patterned fields produced different mood states.  One of them improved mood and vigour, compared to the sham-field.  Attributing these results to patient suggestibility leads inevitably to the conclusion that  depression can be treated through suggestion, a conclusion not supported by any evidence nor predicted by any hypotheses.

We have also shown (Corradini et al.  2013) memory enhancement and  clear changes in delta and theta power over the temporal lobes from magnetic field stimulation (and more accurate brain wave measures, such as QEEG), using a completely separate method for producing the God Helmet’s quiet magnetic signals.  Eliciting the same effects with both different hardware and software also allows confirmation that our results that cannot be attributed to hardware artifacts.

However, the most powerful demonstration that the electromagnetic effects are not due to suggestion is the effect upon cells. We have found in controlled studies that the same pattern using in our sensed presence experiments slows the rate of a variety of different types of cancer cells in cultures (Hu, et al., 2010, Bruckner, 2015). These fields inhibited only cancer cell growth but did not retard the growth of normal cells.  We have found this same field that produced the sensed presence works by very specific channels within membranes that allow calcium to enter the cell (Buckner et al, 2015). The timing of the point durations that compose the specific field pattern must be precise or there is no effect.

Our studies using lab rats cannot be attributed to suggestion as rats cannot be said to be “suggestible”.

Nevertheless, we carry out blind analysis of rat brain sections in our rat studies, in which the investigator does not know which brain regions may have been affected by a procedure or the magnitude of the differences predicted between the rat brains exposed to the magnetic fields and those which were not (Fournier, 2012). In rat studies investigating differences in rat behavior following stimulation with magnetic signals, the experimenter observing their behavior is kept blind to the experimental condition (Whissell, 2007, McKay, 2004, Bureau, 1994, Babik, 1992).  Our examination of microscope slides from rat subjects and controls is also done under blind conditions (Cook, 1999). We have also carried out similar procedures with worms (planarium – Dugesia sp.) (Mulligan, 2012).

The false impression that our effects come from suggestibility of our experimental participants originates from  a paper published by Granqvist et al..  That publication reported a flawed attempt at replicating our work.  In that case our neural stimulation signals were run at too high a velocity (their computer wasn’t calibrated to the software) and for too short a time (only ten minutes instead of the twenty we normally use as the minimum stimulation).   There were other issues, but these were the most significant.  Granqvist, et al. tried to explain the difference between our results and theirs by speculating that our results were due to suggestibility in our subjects. Note that Granqvist (et al.) did not actually measure their subject’s suggestibility.   Their explanation is entirely speculative and ultimately incorrect.

I hope this blog will clarify that we are fully aware of the need to prevent experimenter suggestions and that our results are not due to to suggestibility in our subjects.

Replication of God Helmet experiment and many other of our results. – a Blog by Dr. Michael A Persinger.

200px-Laurentian_University_CoA.svgMuch of our work, including with the God Helmet, has indeed been replicated. Claims to the contrary are mistaken . – A blog by Dr. M.A. Persinger.

Question: Have any God Helmet effects been replicated?  Have other results from your lab have seen replication?

Answer. Yes.  Every major discovery we have published that was considered “novel” has been replicated when the researcher followed the correct procedure.

A replication of God Helmet effects we have also reported in the literature was published in 2014 by a pair of Brazilian researchers (Tinoco, et al. 2014).  Their report very closely replicates one of our early studies (Richards & Persinger, 1993), using the same analytical method that distinguished subjects from controls.  That study concluded that it supports the contention that its results and those reported in our research publications are “attributable to the fields and their configurations, not to suggestibility”.  This refutes the claims that our results come from subject suggestibility.  These mistaken claims come from a researcher (Granqvist et al.) who didn’t use his equipment properly, so it yielded no results.  To explain his failure, he claimed that we used improper methods with suggestible subjects.  In fact, we do use placebo controlled, double-blind methods.

I and my colleagues have also answered these claims formally in publications in Neuroscience Letters, using data from 407 subjects. 

We have replied to points raised by Granqvist in debate in a publication showing that the (experimental facilitation) of the sensed presence is predicted by the specific patterns of the magnetic fields, not by suggestibility.

In addition, we’ve reviewed the methodological differences (between our methods and those used in the Swedish Research group’s flawed work) informally online.

The Granqvist et al study was not designed to be a replication. They did not use the well-known helmet but instead employed a device we made for them as a prototype so they could study PET (Positron Emission Tomography) effects. This is what they claimed they were going to do when they visited the laboratory, and that was what we had in mind when we gave them their instructions for its use. They did not follow our precise timing procedures, needed to generate the fields. The effects do not occur without this precision timing.  Granqvist et al presented the fields in a non-optimal manner, and their scores for their sham and treatment groups were the same as the scores for our sham groups.  Effective magnetic fields are sensitive to the complexity of the timing of their components, just as chemical actions depend on the exact shape of the chemicals being employed. It is like changing a component of a drug and wondering why it does not work.

Granqvist wrote: “Such weak fields are considered unable to induce currents strong enough to depolarize neurons. Thus, the mechanism through which weak complex field(s) … may work remains obscure, but the waveform of the field has been suggested to be crucial” (Granqvist, 2004).  In fact, there is nothing obscure about how the fields work in the brain.

One of the pioneers in biological aspects of magnetic fields, Joseph Kirshvink (1992 A) wrote:  “A simple calculation shows that magnetosomes [chains of magnetic particles] moving in response to earth-strength ELF fields are capable of opening trans-membrane ion channels, in a fashion similar to those predicted by ionic resonance models. Hence, the presence of trace levels of biogenic [produced or brought about by living organisms] magnetite in virtually all human tissues examined suggests that similar biophysical processes may explain a variety of weak field ELF bioeffects”.

Our brains are richly populated with crystalline magnetite, containing 5 million such crystals per gram (Kirschvink, 1992 B).  In the vernacular, our fields work because these crystals move in response and because the information encoded in their movement (coming from our signals); their “patterns”, interacts with the magnetic fields that appear as a consequence of the brain’s electrical activity, a “field to field” effect.  Imagine the sun has a storm, making it’s magnetic field pulse slowly.  Here, on the earth, we would have geomagnetic storms, as pulses from the sun’s stormy field is added to that of our planet. We have found this same field that produced the sensed presence works by very specific channels within membranes that allow calcium to enter the cell (Buckner et al, 2015). The timing of the point durations that compose the specific field pattern must be precise or there is no effect.

Notwithstanding the explanation for the effects of the fields, we also know of at least a dozen researchers who have observed measurable effects from  low-intensity magnetic fields that are significantly weaker than TMS.  These corroborate our reports of measurable bioeffects from weak magnetic fields and demonstrate that depolarizing neurons is not the only way magnetic fields can influence the brain.  We also did a study to demonstrate the permeability of the skull and cerebral space to magnetic fields (Persinger & Saroka, 2013).

Our work has been replicated and confirmed (Tinoco, 2014), which appears to resolve these issues.  We look forward to further studies in the field.

Our analgesic effects from weak applied magnetic fields, beginning in 1994 (Fleming, et al., 1994, Martin, 2004,  Gallic, 2007) were replicated by Thomas, Prato & Kavaliers in invertebrates (Thomas, 1997), rats (Shupak, 2004),  and humans (Robertson, et al., 2010).  A major review by an Italian research group (Seppia, et al., 2007) has demonstrated not only the effectiveness of these fields but their biochemical pathways.  Similar research has been done by many others (Bao, 2006, Kortekaas, 2014,).  Our work on these effects continues up to the present (Murugan, 2014).

The Tectonic Strain Theory has seen a number of replications, corroborations, and validations.  In fact, this work has been carried out  by several independent researchers.

The same is true for our work on geomagnetic influences on paranormal events and geomagnetic influences levels.

My original work (Persinger, 1969) concerning the effects of rotating magnetic fields upon fetal development in rats was replicated by Ossenkopp (1972).

My quantitative demonstration that proportion of global warming is related to solar corona expansion and trends in geomagnetic activity rather than only CO2 (Persinger, 2010) has been replicated by several researchers, including Sudhir (2012) and Wilson, (2014).

Our histopathological analysis of calcium aggregates in brain from excessive seizure damage (Lafreniere et al, 1992) was replicated by Japanese researchers (Mori, 2000).

Our LORETA measures concerning mental time travel, that is measuring memories of experiences from the past and present and pre-experiences of the imagined future (Lavallee, et al., 2010) are consistent with what many others have measured, including Irish (2013).

It seems that one researcher did not replicate one of our results, and online commentators have taken this to mean that none of them have been replicated.  This, in turn was distorted to imply that none of them could be.  I have little doubt that this chain of rumors and distortions has its basis in the way some have been offended by my work on religion.  Religious believers don’t want to accept that the brain could be instrumental in religious belief, and “new atheists” are offended by the idea that religion and religious experiences reflect processes intrinsic to the human brain, and can thus be considered as intrinsic to our species.

Anyone who has taken the time to precisely recreate the experimental or analytical conditions have replicated and extended our results.

I hope this blog will clarify that much of our work has been replicated and that we look forward to persevering in our efforts.

God Helmet Experiments use Blind Protocols and Placebo Controls – A Blog By Dr. M.A. Persinger

God_helmetOur God Helmet experiments employ double-blind conditions and placebo protocols – A Blog by Dr. Michael A. Persinger.

Our critics are mistaken when they claim we do not use proper controls.  We are committed to the scientific method, especially in laboratory experiments, including subject blindness, experimenter blindness, control groups, and blindness by those who analyze our data.

Question:  What are your standard double-blind and placebo controlled protocols?

Answer:  Expectancy and confirmation bias are always important variables when human beings are measuring or being measured. Most of our major experiments over the last three decades with the sensed presence were double blind.  For a placebo, we use a “sham” or absent magnetic field, which we create by disconnecting the solenoids (magnetic coils) from the signal source.  We also exploit all ways and means for ensuring that our subjects are not given any suggestions as to the purpose of the experiment.

Subject Expectations

The subjects volunteered for a relaxation study and were told (via the consent form) they might be exposed to a weak magnetic field. Four to six weeks prior to their participation, the subjects had completed intake questionnaires.  Some critics have mistakenly said that our questionnaires (which asked about some spiritual and otherworldly experiences and beliefs) were administered immediately before the experimental sessions, and that this introduced inadvertent suggestions. In fact, our standard procedure is to separate the questionnaires from the sessions by an average of a month.  They are eventually invited to participate in a “Relaxation Experiment”, so they are unaware that the questionnaires given previously have any relation to the experiment.  The subjects are kept in the experimentally blind condition.  They are not influenced by expectations when coming into our lab.  The lab itself looks like a busy workplace, and is not decorated with religious or spiritual images.

Blind Protocols

The experimenter, usually an undergraduate or graduate student, who runs the experiment is not aware of the true hypothesis or mechanism.

One summary of our work with the sensed presence is our publication: “The sensed presence within experimental settings: implications for the male and female concept of self” The Journal of Psychology, 2003, 137, 5-16.
https://pubmed.ncbi.nlm.nih.gov/12661700/

Here is a very brief summary of that experiment, with its 50 male and 50 female subjects.

In this study, we used a signal derived from burst-firing in the amygdala, applying it over the temporal lobes via a set of four solenoids over each temporal lobe.  We rotated the signal by turning them on and off in sequence.  All of this was built into the hardware, built by Stanley Koren (The God Helmet) or coded into the software that drives it, written by Stanley Koren.  We applied the signal for 10 minutes, gave it a 5 minute break, and applied it for another 10 minutes.  This was done to avoid habituation.

We observed  double-blind conditions, as one can see in the research report:

“All participants were tested by experimenters who were not familiar with the purpose of the experiment.”
“The participants were told that the experiment was concerned with relaxation.”

Note that in some experiments, subjects were told that the experiment concerned memory.  The relaxation and memory suggestions kept the subject in an experimentally blind condition.

The experimenter ran different patterns of magnetic fields created by Professor Stan Koren and me.  Once the results were collected they were analyzed routinely by SPSS  (statistical analysis) software.

Women reported more frequent experiences of a sensed presence than men did , and men were more likely than women to consider these experiences as “intrusions” from extrapersonal or ego-alien sources. Both effects were predicted by one of our hypotheses (vectoral hemisphericity) and the known neurologically-based cognitive differences between right-handed men and right-handed women.

The point here is that we do in fact use double-blind conditions, and claims to the contrary are simply not true.  Other examples, referenced here, include Richards (1992) Persinger (1994), Healey (1996), Persinger (1999), Persinger, (2002) Booth (2005), Tiller (2002), Corradini, (2014).  I have emphasized this in my response to Pehr Granqvist (who made critical technical errors with our equipment, and alleged that our results were due to improper blinding and subject suggestibility), as follows:

“In all of our major studies, involving more than 400 subjects, during the last 20 years the subjects were not aware of their experimental conditions and experimenters were not familiar with the hypotheses being tested or both were not aware of the experimental condition. Subjects had volunteered for “memory” or “relaxation” studies and were randomly or serially allocated to conditions. The “sensed presence” issue was never discussed. The person generating the hypothesis never had direct contact with the subjects.” (Persinger, 2005)

Regrettably, online critics often fail to include this critical reply to Dr. Granqvist.

Let me underscore that we have applied double-blind protocols in our “sensed presence” studies, (to make the differences in stimulation explicit) by quoting another of our papers:

“Under double blind conditions, the subjects who were exposed to the burst-firing pattern presented over both hemispheres or the right hemisphere reported more sensed presences than those exposed to the sham-field [control] or to left hemispheric presentations. Subjects in the latter condition reported fewer sensed presences than the sham-field controls. (Booth, 2005 B)”

Here, stimulation of the right hemisphere is compared to both stimulation of the left, and to controls.  This method allows greater certainty for our results.

Moreover, we often employ “blind” analysis of EEG and QEEG data, in which the person carrying out the analysis does not know what hypothesis the data is intended to study (Makarec, 1990).

In our rat studies, we also carry out blind analysis of rat brain sections, in which the investigator does not know which brain regions may have been affected by a procedure, or the magnitude of the differences predicted between the rat brains used in the study and those which were not (Fournier, 2012). In rat studies investigating differences in rat behavior following stimulation with magnetic signals, the experimenter observing their behavior is kept blind to the experimental condition (Whissell, 2007, McKay, 2004, Bureau, 1994, Babik, 1992).  Our examination of microscope slides from rat subjects and controls is also done under blind conditions (Cook, 1999). We have also carried out similar procedures with worm (planarium – Dugesia sp.) studies (Mulligan, 2012).

” …a total of 10 undergraduate students participated in measuring the worms’ activity; the students were unaware of the experimental conditions, that is, the study was completely “blind”.”

When we analyze the congruence between intuitively-derived narratives from individuals with exceptional cognitive skills and actual information, we use groups of student “raters” who compare the two data sets, and rate the degree of congruence.  All raters are “blind” in that they don’t know anything about the circumstances under which the narratives were derived, or the overall purpose of the experiment (Hunter, 2010).  We also employed the same technique to assess the accuracy of remote viewing by the artist Ingo Swann using graphic images he sketched during remote viewing sessions, augmented by our “Octopus” apparatus (Persinger, 2002, B).  In a related case history, we attempted to interpolate a specific image from a collection of art prints into the dreams of another.  The “agent”, who repeatedly viewed a randomly-chosen (based on dice throws) art image, and was the only one who knew which image was being used.

“The interviews were conducted double blind; neither the percipient nor the experimenters knew the identity of the target or the pool of art prints from which the target had been randomly selected.”

The results demonstrated that greater accuracy was associated with lower geomagnetic activity.

Placebo Controlled, Double-Blind Studies.

Our placebo controls are created by using inert electromagnets (solenoids).  These are not attached to the signal source.  The experimental procedures are identical in all other respects.  We also use our placebo fields  in conjunction with double-blind conditions in our studies.  Here are a few examples:

  • Corradini’s (2014) study facilitating declarative memory
  • Fournier’s (2012) experiment with prenatal rat hippocampus stimulation
  • Mulligan’s (2012) study with planaria.
  • Whissell’s (2007) experiment on the interactions of nitric oxide and seven hertz magnetic fields.
  • Booth’s (2005) sensed presence study.
  • My own study on increased alpha activity from the left hemisphere with stimulation with our burst-firing pattern (Persinger, 1999).
  • My study on enhanced hypnotic suggestibility (Persinger, 1996).
  • A study that assessed the pleasantness of a long-term potentiation signal (Persinger, 1994).
  • A study of coherent responses to Reiki between practitioners and clients (Ventura, 2014)
  • An experiment with altered state experiences with circumcerebral magnetic stimulation (Collins, 2013)
  • Lowering depression and increasing alpha activity in the frontal lobe. (Corradini, 2013)

Sham fields are also used in our studies with cell cultures (Murugan, 2014 A), water Ph (Murigan, 2014 B), Obesity in rats (St-Pierre, 2014), Suppression of Cancer cells, (Karbowski, 2012), energy storage in water (Gang, 2012), planeria studies (Gang, 2011)  and scores of other studies that didn’t use human subjects.

The issue of double blind and placebo control is less important with our modern technology because of the availability of normative (“averages”) for different states, including placebo response states.  Comparing the results of our EEG studies to standard normative EEG states allows us to make inferences that would have required baseline (control) readings just a few years ago (Congedo, 2010).

During the last 5 years, quantitative electroencephalographic measurements by computer and the algorithms to compute distributions of power within the volume of the brain for different frequency bands have become available, and these have revealed that different patterns of fields, delivered to different sides of the brain, produce specific patterns regardless if the person knows if a field is presented or not (Saroka, 2013). Placebo effects produce very specific patterns that are not the same as those associated with either the field presentation or the field plus sensed presence effect.

In spite of claims to the contrary, we do use placebo controls and blind experimental conditions.  Our emphasis has been on quantifiable data, replication, and blind conditions, wherever possible and appropriate.  We remain committed to the scientific method.

I hope this blog will clarify our use of blind conditions, placebo controls and suggestion in our laboratory.

Replications of our work on Geomagnetism and Paranormal Phenomena – A Blog By Dr. Michael A. Persinger.

Several researchers, including myself, have observed correlations between geomagnetic activity and reports of paranormal phenomena. A blog by Dr. M.A. Persinger.

Question: It has been said that your work on the effects of geomagnetic variables on paranormal phenomena “has not been replicated”. Is this true?Dr. Michael Persinger

Answer: No; Our results have been replicated repeatedly.

Confused claims that my work (on the effects of geomagnetic influences on paranormal phenomena) has not been replicated are based on the mistaken belief that its based on experiments.   Instead, the results are based on statistical analyses (replication procedures are for experiments) correlating a wide range of data with geomagnetic states.  To validate a statistical study, one has only to obtain the data, and perform the calculations.

The “geomagnetic effect” has been found in a variety of anecdotal data throughout recorded history.  The experimental dream psi studies from Ullmann and Krippner (1970) were done almost 50 years ago.

For decades after that, groups of researchers, including myself and my colleagues, have investigated the contributions of the geomagnetic field to paranormal phenomena.  Each working independently, we have replicated and extended one another’s work.  There are a few differences in what we’ve found.  Replication and significant convergences in results are commonplace in this field.

Spottiswoode (1997) reported that unusually high effect sizes may be observed in trials with anomalous cognition (PSI, ESP, etc) occurring during specific windows in sidereal time when geomagnetic fluctuations are also minimal.  This confirms our finding that geomagnetic quiet is conducive to these kinds of experiences.  The same author (1990) also reported negative correlations between scores in free response anomalous cognition experiments and geomagnetic fluctuations, confirmed in four datasets which showed significant anomalous cognition.

Adrian Ryan has explored the correlations we have seen between geophysical activity and hypothesized that ESP effects may be due to geomagnetic pulsations, a line of research that both replicates and extends some of our efforts (Ryan, 2008).

Researchers Haraldsson and Gissurarson (1987) studied the scores from 70 Ganzfeld sessions (telepathy-clairvoyance) and found they related significantly to high geomagnetic activity of the day prior to the experimental sessions but not to the geomagnetic activity during the day of the sessions. The same relationship was found in experiments which consisted mostly of 80 trials with clairvoyance computer games per subject.  Their results partially confirmed our earlier findings (based on the Tectonic Strain Theory of paranormal events) that spontaneous paranormal experience tend to occur on a day of low geomagnetic activity which is preceded by days of high geomagnetic activity.

Lipniki (2009) replicated the geomagnetic effect without referring to psi effects in a case report where dreams from low geomagnetic activity periods were found to be significantly more bizarre than dreams from periods with high geomagnetic activity .

Another case history implies a strong correlation between sleep paralysis and geomagnetic quiet.   Conesa (1995) reported that periods of relatively quiet geomagnetic activity were significantly associated with an increased incidence of sleep paralysis episodes, and also (Conesa, 1997) dream vividness.  Moturi et al., (2013) also noted correlations between geomagnetic states and sleep paralysis.

In a study done during the quietest geomagnetic year in a century, small correlations were found with male subjects, who showed higher psi scores when the geomagnetic field was more active.  However, in confirmation of our results, the participants with the highest temporal lobe questionnaire scores showed the strongest correlation of psi with geomagnetic activity (Roney-Dougal, 2014).  This corroborates our early finding that PSI effects are most probable during times of geomagnetic quiet.  We have published several papers showing this effect, including a meta-analysis spanning 60 years of studies (Berger, 1991).  It also replicates our result that Temporal Lobe Signs are higher for people reporting PSI skills and experiences. (Persinger, 1990)

The “geomagnetic” effect as inferred from solar wind velocity was reported by Randall and Randall (1991), who examined data from the 19th century on hallucinations and magnetic disturbances.  These were found to exhibit a direct and statistically significant correlation.  It’s easy to see how this corroborates our work correlating geomagnetic activity with paranormal, PSI, ESP and other anomalous experiences when we recall that changes in solar winds are one of the primary sources for geomagnetic variations.

Our work with the effects of elevated magnetic field strengths (rather than geomagnetic activity) has been replicated by JJ Braithwaite (2004), who reported that  That “the overall magnetic field strength (amplitude) is greater at areas of interest [areas generating higher numbers of reports of paranormal perceptions] relative to baseline areas”.  The same researcher (2005) observed the same effect in a “haunted bedroom”.  This corroborated and extended of our results in it’s observation of “large static inhomogeneous magnetic field and complex temporal distortions in the time-varying (AC) magnetic fields”.  We have seen (Persinger, 1997) that similarly anisotropic structures within both the geomagnetic field and in our complex magnetic stimulation fields also contribute to their subjective effects.

Our work on the association between geomagnetic and paranormal phenomena has also been replicated by Roll (2000) who made recordings of the local geomagnetic fields (GMFs), electromagnetic fields (EMFs), and ion densities in putatively haunted locations. On the basis of previous studies he predicted that the sites would exhibit anomalous EMFs or GMFs. Ten out of twelve of the sites did show such anomalies.

It’s also worth noting that in addition to the paranormal and ESP effects noted above, the scientific literature includes many studies of the effects of geomagnetic activity on medical and psychiatric disorders and issues.  These include stress (Rapoport, 1998 ), suicide (Berk, 2005), blood pressure (Dimitrova, 2004) psychiatric admissions (Raps, 1992), stroke (Feigin, 2014), changes in EEG profiles (Novik, 2013) and errors in performing laboratory tasks (Binhi, 2009).  The geomagnetic field makes these effects more likely, but doesn’t cause them.

I hope this blog will clarify the value of studying geophysical influences on human cognition and health.

The Tectonic Strain Theory and French’s “Haunted Room” Experiment – a Blog By Dr. Michael Persinger.

My Tectonic Strain Theory is alive and well – a Blog by Dr. M.A. Persinger.

Despite claims to the contrary, there have been a number of replications, corroborations, and validations of my work with the Tectonic Strain Theory from several independent researchers.

Misleading claims that my work with Tectonic Strain Theory has not been replicated are based on the mistaken belief that its based on experiments.   Instead, the theory is based on a series of statistical analyses (replication procedures are for experiments, not statistical arguments).  To “replicate” a statistical study, one only has to obtain the data, and perform the necessary calculations.  In such a case, it would be more properly said to have been “corroborated” or “validated”, not replicated.  Critics, wanting to disparage my work in this field, have pointed to a “Haunted Room” experiment, and incorrectly implied that it was a test of my work on the relationship between geomagnetic conditions and the propensity to report paranormal and other unusual experiences.

Question: Does ChristopherGreat_Balls_of_Lightning French’s “haunted room study” have anything to do with your tectonic strain theory or the way you study the role of the earth’s magnetic field in paranormal experiences?

Answer:  No.  French’s experiment has little (if any) relationship to the tectonic strain theory, which explains with the creation of luminosities (“lights in the sky”) before earthquakes.  We have found that these correlate with UFO sightings.    We’ve also seen similar correlations with apparitions and other phenomena.  In brief, this theory tells us that electrical and magnetic fields produced by the bedrock while its being strained by the pressure that’s eventually discharged by an earthquake create luminous displays, like earth lights, ball lightning, and sometimes dramatic lights in the sky.  We also find that these fields can create unstable conditions in the brain, especially the deep portions of the temporal lobes.  This instability can lead to hallucinatory experiences which people interpret in terms of their cultural and learning history as well as their private beliefs, so they are interpreted and then seen as spirits, the Virgin Mary, angels, alien spacecraft or ghosts.  This idea has recently been independently proposed by another researcher, who hypothesizes that “ball lightning” may induce hallucinations (Edwards, 2010).   My first publication in the field (1976) used the same concept to explain UFO reports.

The God Helmet is an example of “complex magnetic” neural technology.  Trying to imitate its effects, French’s experiment consisted of trying to construct a “haunted room” by building a room and filling it with magnetic signals and infrasound.  The experiment did not succeed.  French is a well-known skeptic, but not experienced in the proper use of the “complex magnetic” neural stimulation we use in our lab.  We have been able to successfully perform several experiments inducing paranormal experiences,

We have also induced apparitions, including a ghost, in our lab.

French’s experiment used a wave pattern that could not have created the conditions for synthetic paranormal experiences because he was not able to generate the appropriate point durations we use in our lab.  The point durations (how long each bit of the signal lasts) are so important that altering them makes them ineffective. I e-mailed him and offered to share the equipment but he declined, and instead chose to develop his own apparatus, including a procedure in which “The … burst pattern was generated by constructing a table of values from (a) graph of the waveform used and then converting these numeric values…” (French, et al., 2008)

The graph French refers to here is a graph of point (X axis) and Field strength (Y axis).  However, the graph doesn’t display the durations of the points on the X axis.  We have kept that specific parameter flexible in order to allow experimentation with different point (or pixel) durations.  Incorrect point durations will yield ineffective signals.  Our many experiments with varying point durations have shown us that precision in this regard is critical.  A metaphor may be helpful here.  It is as though we hear the phrase “clean the turpentine brushes” as “queen a serpentine buses”.  The majority of the phonemes may be correct, but the information content will be absent, and the communication cannot initiate an appropriate response.

My colleague Todd Murphy, who has developed multiple systems that effectively deliver our (complex magnetic) signals points out in a brief web posting that Christopher French used the “Goldwave” audio editor to render his signals.  Professor Murphy used this same method early in 1999 for the first draft of his signals, which did not work.  His signals became effective only after he introduced his proprietary methods for developing the signals the following year.  We validated their effectiveness in a paper published in 2004.  The techniques used to render effective audio equivalents to our (God Helmet) signals were not applied in French’s Study.  Prof. Murphy informs me that his signals were drafted eighteen times overall.

French (at al.) edited his signal “into a 16-bit wav file using Goldwave (software) at a sample rate of 1000 Hz for playback via the computer’s soundcard.”  It may be relevant that Murphy’s signals do not use this sampling rate.

Subjects in our experiments are informed that they are participating in a “relaxation experiment”.  French’s subjects were “… informed in advance that they might experience unusual sensations whilst in the chamber …”.  The difference in “priming” may have predisposed his subjects towards apprehensiveness, and facilitated arousal, which we have found reduces effect sizes.

It may also be relevant that the background sound levels in the French study were significantly above the values we require to obtain the sensed presence. That’s why we employ the echoic (acoustically silent) chamber.  When we first started the research 30 years ago we employed New Age Music while the fields were presented and found the sensed presence was actually reduced. That’s why music was removed from the protocol. In addition, because the temporal lobes are discerning the applied fields (as are neuroimaging profiles indicate) sound pressure from any source is also represented within the temporal lobes, and interferes with the effect.  A significant portion of default mode temporal lobe excitation functions to monitor ambient sound.  Employing a truly silent environment recruits this activity into the neural responses to the signals.

Perhaps the most important difference between our procedures and those employed by French (at al.) is that they used a room to apply the signals, while we utilize a helmet, designed for the human head.  Our equipment allows us to apply our signals to either the left or right temporal lobes or both.  This allows us to perform our stimulation sessions with more than one hemispheric presentation.  Our “sensed presence” protocol involves stimulation of one hemisphere (the right) with one signal (derived from a “chirp” sequence) followed by another signal over both hemispheres.  This optimal design for eliciting the sensed presence has been published in the literature.

Utilizing an entire room to apply the signals means that 1) brain regions outside the temporal lobes are not excluded from the stimulation, and 2) it becomes impossible to target only one of the temporal lobes, as we commonly do in our work.  In fact, we have applied our signals in the context of a whole room, and found that whole-body exposures have minimal effects, if any, even when the signals are correctly configured.  We did not publish the study, due to its trivial character, and the non-trivial efforts required by scientific journals for publications.

There are a few online sources that mistakenly claim that our work in this area has not been replicated.  This is not the case.

Several kinds of research combine to support our geophysical research in this area.  The US Geological Survey has reported earth lights appearing with earthquakes.

Several researchers have confirmed our ideas about “earthlights”, and the idea has, in fact, become commonly-accepted (as for example in Smithsonian Magazine), though there continues to be debate on the subject.   A direct replication of some of my research appears in a study by Thériault (2014) titled “Prevalence of Earthquake Lights Associated with Rift Environments” in Seismological Research Letters.

NASA now recognizes earthquake lights as earthquake precursors (Bluck, 2001).

“When the rocks in the Earth’s crust crackle and buckle under the onslaught of tectonic forces, the charges that are dormant in them are set free. They give rise to a dazzling array of phenomena, long known to mankind and even part of folklore in earthquake-prone regions around the globe,” said Freund. “These phenomena range from anomalous electric and magnetic signals, to ‘earthquake lights’ that illuminate the mountain tops and strange animal behavior as well as ionospheric effects that impact how radio waves travel over long distances.”

Japanese researchers (Takaki, 1998) have also observed “Change in seismic stress releases piezo-compensating, bound charges due to changes in the piezoelectric polarization of quartz grains in granitic rocks, which produces an intense electric field at the fault zone. The excited or ionized molecules by free electrons accelerated under the electric field produce luminous phenomena in the atmosphere” They also proposed “A model of dark discharge in the atmosphere before a large earthquake was proposed to elucidate the mechanism of generation of earthquake lightning and related electroatmospheric phenomena. Change in seismic stress releases piezo-compensating, bound charges due to changes in the piezoelectric polarization of quartz grains in granitic rocks, which produces an intense electric field at the fault zone.

Researchers at Rutgers University have carried out experiments that support the concept of earthquake lights by emulating earthquake conditions in the lab (Shinbrot, 2012).  These are reported as often being mistaken for UFOs, as predicted by my tectonic strain theory of unusual events.

John Derr, a pioneer in this field of study, was one of the first to propose that geophysical strain could explain earthlights, and other luminous phenomena (Derr, 1986).

Paul Deveraux has published several books of his independent investigations showing the association of these earth lights with paranormal phenomena, which constitutes a replication and confirmation of my work in this area.

To summarize, Christopher French’s “haunted room” experiment was not a test of the tectonic strain theory in any way.  This theory has been independently validated, both in its geophysical hypothesis (that geological strain prior to earthquakes produces earth lights) and its power to explain paranormal (apparitions and UFOs) phenomena.

The theory met with criticism from one researcher soon after it was published, and I published a reply.

I hope this blog will help to clarify my Tectonic Strain Theory, and to underscore that I am far from alone in these concepts.

Richard Dawkins – Alcohol and the God Helmet don’t mix. – Dr. M.A. Persinger’s Blog

Dawkins had been drinking before his God Helmet Session, and that interferes with its effects – a Blog by Dr. Michael Persinger.

Question: Richard Dawkins is seen drinking wine or wine mixed with soda water (a “Wine Cooler”) before his session with the God Helmet in the BBC video showing his visit to your lab. Had he been drinking before the session? Will alcohol interfere with the God Helmet’s effects?Dawkins_Wine_cooler

Answer: Yes, he had been drinking. The scent was easily noticed. In addition, he was obliged to sit in hot lights within the chamber for almost an hour as the BBC director managed several television studio details before the experiment began. This forced us to deviate from our typical protocol where the person walks into the dimly lit chamber and we begin the experiment within a few minutes. We have found that intoxication, particularly ethanol, interferes with the experimental induction of the sensed presence. That is why we always employed an EEG monitoring at the time of the exposure. If the brain state is not optimal, similar to the calm or relaxation that facilitates meditation or prayer, the fields do not optimally interact.

In addition, Dawkins had scored low for temporal lobe sensitivity, as mentioned on several web pages.  Ordinarily, there are ways we can compensate, but these conditions made it difficult.  Getting a subject to relax can take time before the session begins, and on that occasion, we were already pressed for time.  Interested readers can see “The neurotourist: Postcards from the Edge of Brain Science”, where author Lone Frank, who visited our lab, tells how her EEG showed she wasn’t in the right frame of mind, and we waited until our EEG showed she was ready.  BBC procedures and Dawkins’ perfectly reasonable impatience made this impossible.  I have not mentioned these aspects of Dawkins experience in our lab as a courtesy to those involved, but the large and growing number of web pages discussing this case has made it clear that withholding these details now serves to distort the truth.

Two other prominent skeptics, Dr. Susan Blackmore and Michael Shermer, had phenomena-rich God Helmet sessions in our lab.  Michael Shermer (editor of Skeptic Magazine) said that he had “… not only a sensed presence experience but an out-of-body experience as well”.

Dr. Susan Blackmore said:  “When I went to Persinger’s lab and underwent his procedures I had the most extraordinary experiences I’ve ever had,” she says. “I’ll be surprised if it turns out to be a placebo effect.”   These are relevant in view of the mistaken online claim that the God Helmet doesn’t work on skeptics.

Nevertheless, in spite of these limitations, Richard Dawkins did have some effects, but they were somatic, and not cognitive or affective, as we usually see.  He reported a mild dizziness and twitching in his legs and a “twitchy” feeling in his breathing.  These sensations often appear as precursors to the sensed presence experience.

I hope that this brief blog will lend clarity to this well-known case history.

My theories are not based on religiousness in epileptics – Dr M. A. Persinger’s blog

Question: Are “microseizures” (a concept you have used to help explain religious experiences) actually epileptic events?  (A Blog by Dr. M.A. Persinger)

Answer: No, although they do have some things in common with epileptic events (seizures) because they originate from the same source; i.e., moments of instability in the temporal lobes, most particularly in it’s deeper (limbic) regions.  Most phenomena that share a common cause are distributed along a continuum (or spectrum) of intensity with degrees of “how much” (or how strong).  For example, a few times during their lives, for brief periods, most people display the symptoms that define depression, thought disorders (such as schizophrenia) and personality disorders. However, it is only when the symptoms dominate the person’s behaviours more or less continuously, that the condition is considered abnormal.  To employ a metaphor, ordinary religious experiences rely on brief “unsettled” conditions in the temporal lobes, but not full temporal lobe epileptic seizures.

“Microseizures” is a term I borrowed from Goldensohn (1975, 1983) who described epileptic activity from the small columns within the cerebral cortices induced by surgical electrodes (that was not evident by typical scalp brain wave activity) to indicate subclinical electrical patterns that shared some features with (but were not the same as) epileptic events.  A more recent publication (Stead, et al., 2010) describes Goldensohn’s findings as follows:

“They demonstrated focal evolving microepileptiform discharges after penicillin injection on single electrodes in an array of electrodes spaced 2 mm apart with no reflection of the discharges on adjacent electrodes.”

In other words, electrical discharges creating EEG (electroencephalographic) patterns which are similar to epileptic activity can appear from the brain.  These don’t spread to other areas the way true epileptic seizure activity does.  Note that in the above quotation, such activity was read from one sensor, but the other, only two millimeters away, did not detect it.  This has been the primary exemplar of microseizures in my work.  To clarify further, microseizures are non-epileptic events that mimic seizural activity, taking place in exceedingly small (“pinpoint”) volumes of brain space.

My theory of the continuum of temporal lobe lability (offered as an explanation for the wide differences between religious and non-religious personality types and the propensity to report religious experiences) is not based upon the rich literature demonstrating links between religiosity and temporal lobe epileptics (and, more broadly, temporal lobe foci).  This link has been repeatedly observed and is still observed in some populations. Instead, my theory is based on laboratory measurements of normal, non-epileptic people. I think it is important to emphasize that the research began and continues to be focused upon creativity and the factors that allow human beings to adapt to complex and ever changing environments and circumstances. Sensitivity, but without actual epilepsy, at the upper end of the continuum of temporal lobe lability is associated with remarkable creativity.

Many epileptics have had religious experiences, but only a very small minority of people reporting such experiences are epileptics.  Moreover, only a very small percent of all epileptics report such experiences. We can easily understand how the relative importance of religion in human cultures has given them a disproportionate prominence in the literature surrounding the study of the neurological aspects of religion and spirituality, i.e., the field of neurotheology.

The sensed presence is a primary feature of above-average temporal lobe sensitivity.  It has been given different labels that range from the Muses of the Ancient Greeks to the “spirit guides” of contemporary New Age religion and philosophy.  My working explanation is that the sensed presence is the left hemispheric awareness of the right hemispheric equivalent of the sense of self. We have demonstrated the direction effect across the two hemispheres and lobes by neuroimaging.

Religious belief is not an epileptic phenomena – Dr. Michael A Persinger

IDr. Michael Persingers religiosity an epileptic phenomenon? (A Blog by Dr. M.A. Persinger)

Answer: The answer to the question, as stated, is “no”.  The microscopic connections between brain cells which are associated with certain patterns of behavior (These patterns are called personality in the vernacular) are altered by conditions within the temporal lobes that encourage frequent and very specific types of electrical patterns.  Only very extreme brief electrical activity that involve large volumes of the brain defines epilepsy.

Its important to differentiate three components: religious experiences, religious beliefs and religiosity (the propensity for interpreting events in terms of religious beliefs, as well as participating in religious rituals, showing reverence for religious symbols, etc.).  A religious experience will include perceptions that involve multiple areas but particularly the temporal lobes because they contain the amygdala which is involved with meaning and affect and the hippocampus, which is involved with memory.  However, like any other experiences, religious or spiritual events are encoded into verbal images. This involves or “recruits” the frontal portions of the brain.

Even when its subtle, the way a person labels the “cause” of a mystic experience, or what they attribute it to, is supplied by the person’s culture and learning history and this can have a significant effect on how they remember the experience hours to days later.  To offer a mundane example, people often hear words that upset them (for example, during arguments).  After the event has passed, they are very likely to speak of it referring to the words that made them angry or sad, and not a description of the discomfort they created.  The explanation supplants memories of the actual event.  This also happens with religious experiences.   The phenomena are recalled as instances and verifications of the themes in their religious beliefs.

The images associated with the words that we use to label a religious experience, without actively doing anything, strongly affect what we later remember as true.  A religious belief, like all beliefs, is a cognitive strategy.  Religious beliefs attempt to anticipate both events in the world, and our life experiences (including religious experiences) and organize their meaning. Religious belief is different from a religious experience.  A delusion differs from a belief to the extent that it affects the person’s explanations and perceptions of his or her own private world. Religiosity is the degree to which the experience infuses what the person perceives, thinks, and believes about the world and explains the Cosmos.  Delusions have implications about the person who has them, while religiosity includes beliefs about the entire universe, including its origins and eschatology.  Given that science also offers a cognitive strategy for anticipating events and interpreting their significance, maintaining a religious ideational framework (“belief system”) and its accompanying paradigms cannot be regarded as an epileptic phenomenon.

New Edition of “Sacred Pathways: The Brain’s role in Religious and Mystic Experiences”

Sacred_Pathways_Cover_XX_sm

I’ve just finished a new  (second) edition of  Sacred Pathways: The brain’s role in Religious and Mystic Experiences“.  I remain grateful to both H.H. The Dalai Lama, and Dr. Michael A. Persinger for providing forewords to my book.  Although the reader feedback for the book is very positive, a couple have commented that they found proofreading errors, and asked that they be fixed.  I have done so.

In addition, I’ve made smaller additions throughout the text, as well as adding references for many statements.

Preparing the text for the second edition was a very fulfilling job that sent me back to the drawing board, and I learned a few new things along the way.

One important change is that recent evidence shows that only a small portion of the anterior commissure (AC) connects the two amygdala, which makes it even more likely that it would be changed during a dramatic spiritual experience.  Interestingly, most of the AC fibers connect the temporal lobes with each other.  In other primate species, they are exclusively dedicated to connecting the two amygdala to each other.

Another is that there is more emphasis on the role of the frontal lobes in such experiences, especially with respect to their connections to the brain’s reward circuits.

None of these changes call for any alteration in the book’s basic hypothesis, that religious and mystic experiences represent excitement in the “Sacred Pathways” that we evolved to support the death-process, as made explicit in Near-death experiences.

There are a few more illustrations, of brain circuits, some of the saints mentioned in the text, and of Yama, the fascinating lord of The Underworld in the mythologies of India, Thailand, China, and most of Southern Asia.  I’ve also put it into Amazon’s “Matchbook” program, so if you buy the paperback edition, you can get the kindle version for 1/3 of the regular price.  I don’t know why anyone would want to read it in both editions, but Amazon seems to think its a good idea, and they know more about kindle readers than I do.

“Sacred Pathways: The Brain’s role in Religious and Mystic Experiences” is available in paperback.

“Sacred Pathways: The Brain’s role in Religious and Mystic Experiences” is also available in Kindle E-Book
