One of the most fundamental, and damaging, falsehoods in modern science is that all that exists is the physical world, and the closely related concept that the physical brain creates consciousness. Modern neuroscience is contributing to the rejection of this misconception through a set of interesting experiments assessing the action of various psychedelic drugs on the brain (specifically those that influence serotinergic receptors).
Scientific investigations that utilize psychedelic drugs offer measurable and functional outcomes that inform our evolving notions of consciousness and our understanding of the full nature of reality. However, let me be clear from the outset of this article that I do not recommend the casual use of such substances in a non-sacred, recreational setting. In research studies, the quality and quantity of drug administered can be strictly controlled and monitored, which is not the case in most recreational settings where such psychedelics can be dangerous to one’s health.
For purposes of scientific research, they offer compelling findings which mirror the effects of non-drug induced spiritually transformative experiences such as near-death experiences.
First is a report from Imperial College in London in 2012 in which functional Magnetic Resonance Imaging (fMRI) was used to evaluate various brain regions in subjects under the influence of psilocybin, the active principle in psychedelic mushrooms (the genus Psilocybe consists of over 100 species).1 The most remarkable finding of that study was that the activity of major connection regions of the brain was greatly diminished in those who were having the most profound psychedelic experiences, as opposed to the increase in activity anticipated by physicalist scientists who believe the brain creates consciousness and all of experience.
These results were confirmed by a Brazilian study published in February 2015 assessing brain activity through fMRI, this time in subjects under the influence of ayahuasca (which contains the active psychedelic compound N,N-dimethyltryptamine, or DMT, normally present in our brains but in only minuscule amounts).2 Ayahuasca caused a significant decrease in activity throughout the main junctional network in the brain, known as the default-mode network (DMN).
Just this month, the Imperial College group in London refined these observations with another confirmatory study, this one examining the effects of LSD (lysergic acid diethylamide-25), the most potent psychedelic, active in doses of 10s to 100s of micrograms.3 In brief, they report decreased integrity of the DMN and decreased alpha and delta power in another main junctional network, the exact opposite of what one would expect if the physical brain were creating the extraordinary conscious experiences.
The reason these studies are so crucial (and confounding to the materialists who believe the physical brain creates conscious experience) is that they powerfully refute the simplistic and false physicalist notion that the brain creates consciousness. The most extraordinary experiences were reported by those subjects who had the greatest inactivation of their brain’s junctional center network activity, as measured through fMRI and MEG. As the brain becomes less active, internal experience actually becomes more active.
This is completely consistent with my own experience in deep coma due to severe bacterial meningitis (as recounted in my 2012 book Proof of Heaven). As my neocortex was destroyed by the invading bacteria, my conscious awareness greatly expanded to levels unprecedented in my normal waking experiences of my entire life. That shocking reality nagged at me especially in the early months after my coma, at a time I was trying to explain the whole experience as a vast hallucinatory trick of the dying brain (defaulting to my pre-coma reductive materialist scientific beliefs, honed by several decades working as a neurosurgeon).
My doctors knew from the medical evidence in my case that my neocortex was far too damaged to be supporting any mode of robust conscious experience, including any elaborate hallucinations, drug effects or dream states. After extensive review with some of the doctors who cared for me, and with several interested colleagues in neurosurgery, it became apparent that that ultra-reality occurred because the experience was real, although it did not occur anywhere in our 4-dimensional space-time of the observable physical universe.
As is often the case with global media completely steeped in the conventional materialistic paradigm, the press reports about the most recent study falsely trumpeted the opposite of the actual findings. Both the Guardian and CNN focused on some of the fMRI images, but completely missed the astonishing conclusions of the actual study, instead misinterpreting them as showing increased brain activity as opposed to the remarkable decreases in activity the paper actually reports.
Although such scientific investigations into psychedelic drugs are crucial in our evolving notions of consciousness and understanding the full nature of reality, I do not recommend the casual use of such substances in a non-sacred, recreational setting. However, very powerful tools exist for those seekers seriously interested in pursuing the deep mystery of consciousness within us all.
Meditation is a time-proven technique for those seeking to understand the universe by going within. For those who do not yet have a reliable means of meditation I suggest the tools of differential sound frequency brain entrainment I have helped to develop with Sacred Acoustics. Co-founder Karen Newell and I travel the world sharing these tools in our presentations – a list of upcoming presentations is listed here.
We are spiritual beings living in a spiritual universe – we can come to know this fact by going within. Given there is but one Truth we all seek, it should come as no surprise that open-minded science that acknowledges all of the relevant empirical observations (including not only psychedelic drug experiences and epiphanies during meditation, but near-death experiences, shared-death experiences, precognition, after-death communication, death bed visions, out of body experiences, remote viewing, past life memories in children indicative of reincarnation, etc.) should help lead us towards that Truth. This will lead to a necessary synthesis of science and spirituality that is crucial to our evolution as a species and to the well-being of all life on our planet.
