Deja Vu & Other Spiritual Gifts will help you find the spiritual practices that work for you. It also explains how to begin working towards spiritual skills, like healing by laying on hands, psychic perception, communicating with animals, and out of body experiences. It will tell you what the 3rd eye is, and how to ‘open’ it. All these things are a lot less profound and a lot easier to learn than they seem. When the veil of superstition is lifted from these cognitive skills, they become much simpler and more attainable. They may seem more profound when they’re embedded in metaphysical teachings, but the metaphysics actually makes them harder to practice.
The spiritual path in this book is based on neuroscience, not any religious traditions. It uses the shamanic and tribal religions of our first homo sapiens ancestors as a point of reference a few times, because that’s first spiritual path our species adapted to.
If you sense presences when you’re alone, you probably have an aptitude for prayer.
If you often have music running through your head, you will probably have a knack for chanting practices, like the rosary or Hindu Japa.
If you feel your body moving when you’re actually keeping still, you may be able to learn to have out-of-body experiences.
Very few people have all these sensations, but most people have at least one of them. In Déjà vu & other Spiritual Gifts, you’ll find ways of working with them that can make your spiritual life more fulfilling.
Deja Vu & Other Spiritual Gifts will tell you how to begin learning healing by laying on hands, the only kind of healing available for the first generations of humans. It also offers some wisdom from a spiritual healer, who passed it on to the author.
This is an example of applied neurotheology. It puts scientific discoveries about the brain’s role in religious and mystic experiences into practice.
There are about 25 articles on neurotheology on a recently-reorganized page on my website. Most authors on this subject take monotheism (God and belief in God) as the main subject for neurotheology. I think that the mystic traditions of Hinduism and Buddhism are just as important, and there are several articles that cover some of it’s concepts, including enlightenment and reincarnation.
My perspective is based on neuroscience, but the theory of evolution is just as important for me. It’s not enough to see that the brain participates in spiritual experiences. Any explanations that fail to see the adaptive value of spirituality in our evolutionary history fall short of explaining why humans are so often deeply involved with religion, and why some of us aren’t. People who aren’t interested in spirituality are also important part of the story. The brain can take us through mystic experiences, but neurotheology needs to explain why we (or some of us) have them, and that brings us back to the origins of our species.
The religions we see today aren’t the ones neurotheology really needs to explain. The religions of our earliest ancestors may be the best place to look to understand how and why humans are so drawn to religion and spiritual practices, like prayer, chanting, meditation and above all, shamanism.
Among other things, it says that two brain parts are the source for spiritual experiences. These are the hippocampus on the right, and the amygdala on the left. The hippocampus supports trances, meditation, introspection, equanimity and detachment. The left amygdala underpins devotion, intimations of God, angels and spirits, as well as religious joy, rapture, and bliss. We could say that the first is the way of meditation, and the second is the way of prayer.
Differences in personality and ways of thinking (“cognitive style”) that appear when people have their spirituality ‘focused’ in these two very different brain structures create diversity among people. It also means that no single “spiritual path” could (or ever can) work for everyone.
This gave our earliest ancestors many different ways of thinking. People with many different perspectives participated in our ancient tribal councils. In a tribal council, the aggressive and the peaceful both have voices worth hearing. This gave the tribe more options when they were confronted with threats and opportunities.
There were (and still are) big differences in the religious lives of people. On top of this, there are big differences in how ‘spiritual’ we are. Some of us are so involved with religion that anything they say is an expression of their religious beliefs. Others don’t care at all. Our populations include both atheists and the devout, as part of the same (evolutionary) strategy for keeping ourselves alive. Atheists are often ‘linear thinkers’, and religious people are more ‘holistic’. Each type is prone to different mistakes, and when our species was young, they could compensate for each other.
The variety in the kinds of spirituality, and the differences in how interested we are in it, may be the sources for the diversity among humans. And diversity is part of our ‘survival strategy’. Ten people, ancient or modern, will find ten different things to say about a single situation, and this gave our ancient tribes lots of options for responding to it. The tribe would make it’s choice over time, after people had had a chance to talk it over, especially in tribal councils. The saying “many hands make light work” applied to thinking as well as working.
Spirituality may be supported by our brains, but only because our evolution demanded it.
The variety in how much and what kind of religion may be one of the things that makes us human.
Homo Sapiens: The animal that both prays, and rejects prayer.
“Dr. Michael Persinger, known as the developer of the God Helmet, an experimental apparatus that let a few people see God in his laboratory, has published a laboratory report in which a subject had an out-of-body experience immediately after magnetic brain stimulation that lasted only five minutes.” Link (opens in a new window)
Persinger has published a reply to a critical article in a British “pop” psychology magazine (The Psychologist) entitled “Neuroscience for the Soul”. This article perpetuates a few mistaken notions about the God Helmet, as well as some of Persinger’s theories.
For example, Persinger does not believe that spiritual and religious experiences are seizural events in the temporal lobes, and he also rejects the idea that religious belief is an epileptic phenomena.
Richard Dawkins, the flagship author and semi-official spokesman for the skeptical movement, had been drinking before his God Helmet Session, and that’s why he felt so few effects.
The low-intensity magnetic fields used with the God Helmet are strong enough to create striking effects, and this link will take you to a page where you can see that lots of other researchers have seen measurable effects using low-powered magnetic fields on the brain.
Skeptics insist that Persinger’s work with paranormal phenomena (correlating it with geomagnetic measures) has not been replicated.However, it simply isn’t true.
The “Haunted Room” experiment (intended to try to create a synthetic haunted environment) was not a test of any of Persinger’s concepts, in spite of claims to the contrary. The “haunted room” experiment used whole-body stimulation (to try to create an artificial “haunted Room”), while Persinger’s experiments stimulated only the head, and sometimes just one side of it. You can’t stimulate only the right side of the head using an entire room as the stimulator.
Most of the criticisms of Persinger’s theories and ideas resolve into “straw man” arguments. These are arguments that give the impression of criticizing a person’s argument, while actually challenging a position that they never advanced. It creates the illusion of having falsified an opponent’s proposition by covertly replacing it with a different proposition (i.e. “stand up a straw man”) and then to dispute the false argument (“knock down a straw man”) instead of the original proposition. Other straw man arguments are based on substituting a critic’s interpretation of a belief for the belief itself.
There are many other points discussed in Persinger’s published reply, making it worth reading for anyone interested in neurotheology and the many debates that have appeared over the years. You can read it here.
The mistaken claims that our magnetic fields can’t affect the brain ignore the evidence – a Blog by Dr. Michael Persinger.
Question: Is there any truth to the claim that your magnetic fields cannot influence the brain?
Answer: No. Recently, a colleague and I performed an experiment using three materials, each three times as dense and thick as the human skull (wood, saline solution or duct metal) to demonstrate that there is no validity to claims that weak, time-varying magnetic fields applied in this manner are eliminated or significantly attenuated (weakened) by the human skull. The result was straightforward: The fields were not attenuated (weakened) in any way.
Persinger, Michael A., and Kevin S. Saroka. “Minimum Attenuation of Physiologically-Patterned, 1 µTesla Magnetic Fields through Simulated Skull and Cerebral Space.” Journal of Electromagnetic Analysis and Applications 5.04 (2013): 151. (See evidence)
The contention that magnetic fields cannot influence the brain is based on a fallacious interpretation of TMS (Transcranial Magnetic Stimulation), which uses magnetic fields strong enough to depolarize neurons. Typically, these fields are a million times stronger than the kind that surround stereo headphones. This “brute force” approach has several clinical applications. Critics claim that neural stimulation employing fields with lower strengths can’t have any effect. A brief look at the applicable laws of physics and laboratory evidence shows us that this simply isn’t the case.
It should be understood that any contention that magnetic fields cannot penetrate the head are contrary to the laws of physics, which tell us that the head cannot act as a magnetic insulator, because these same laws exclude the existence of magnetic insulation. This has to do with one of Maxwell’s Equations (del dot B = 0). All magnetic field lines must terminate on the opposite pole. Because of this, there is no way to stop all of them; they must all find a way to return the magnetic field lines back to an opposite pole.
This is how it is explained in the theories of physics. When we examine the question empirically, we find that there is a substantial body of evidence showing that weak magnetic fields do penetrate the head, and that they can also influence brain activity. Let me address how this happens.
In classical physics, a changing magnetic field produces an electric field and an electric current. The amount of current depends upon the conductivity of the substance, whether its a copper wire or our brain tissues. That’s how TMS works. However, there is also magnetic energy.
When we apply our magnetic fields, with strengths a million times less than TMS, the energy within the volume of the person’s brain is about a nanoJoule (one billionth of a Joule) per second. When we average this out over the about 100 billion neurons (and their support cells) in the human brain, that works out to about 10^-20 Joules per cell each second. The number is a decimal point followed by 19 zeros and then a 1. This may seem very, very small. Actually, it matches the amount of energy involved when a single nerve cell produces one action potential that contributes to our present-time subjective experience. Moreover, a change in the activity of one neuron can alter the state of the entire brain (Cheng-Yu, 2009) This small quantity of energy is also the same as the amount that binds chemicals to cells through receptors.
However, the values can be enhanced. Our brains are richly populated with crystalline magnetite, containing 5 million such crystals per gram (Kirschvink, 1992 A). They appear in chains (“magnetosomes”). In the vernacular, our fields work because these chained 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 are added to that of our planet. We have found the 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.
One of the pioneers in biological aspects of magnetic fields, Joseph Kirshvink (1992 B) 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”.
The magnetic fields that surround stereo headphones are in the same range, but are not embedded with neural information.
The reader can see 10 examples of magnetic stimulation studies below. Only independent studies are listed. The magnetic stimulation reported in them run from a quarter of the field strengths used in TMS (1 Tesla) to less than a millionth of that value. Each listing displays:

I hope this blog will clarify that the magnetic fields we utilize in the God Helmet can indeed affect brain activity, and that claims to the contrary contradict the laws of physics and are made without examination of the evidence.

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?
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 one of our placebo-controlled experiments, 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 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 are 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 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.
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.
