...terms of a question that's been raging for years, it's the best study to date - an extremely good study," says Dr. Philip Shaw, a research psychiatrist in the Child Psychiatry branch of the National Institute of Mental Health. (See the top 10 bad beverage ideas...
...account for all elements of an NDE, and that we should consider the mind-bending possibility that consciousness can exist independent of a functioning brain, or at least that consciousness is more complex than we suppose. Though NDEs are driven in part by neurochemistry and psychology, says Auckland psychiatrist Karl Jansen, it has "underlying mechanisms in more mysterious realms that cannot currently be described...
...These are the best of times in the NDE field, with research gathering pace and new insights emerging. University of Virginia psychiatrist Bruce Greyson reported recently on a tantalizing investigation into whether the observations people claim to make during an NDE (details of their resuscitation, the color of a nurse's shoes) are in fact accurate. Meanwhile, University of Kentucky neurophysiologist Kevin Nelson theorizes that NDEs are what can happen when a particular sleep state intrudes on the imperiled brain. "I wouldn't say it's definitive," says Nelson. "But it's an intriguing hypothesis that answers a great deal...
...idea that the brain can be retuned to alternative states resonates with psychiatrist Jansen, who's written prolifically on how an NDE (or something closely resembling it) can be induced by an anesthetic drug, ketamine. That NDEs can be induced led him at first to suspect that the spontaneous type was similarly hallucinogenic. Now he's not so sure. Perhaps ketamine and brain stress simply make certain states more accessible. "All our realities are alternative realities," says Jansen. "Nobody sees the world in quite the same way as any other person...
...soon-to-be-published review of the literature, a team of Australian researchers reports, for example, that Chinese NDEs are dominated by feelings of bodily estrangement without all the pleasant stuff, and that the Japanese see caves rather than tunnels. For co-author Mahendra Perera, a Melbourne psychiatrist, these differences don't prove that NDEs are hallucinations, only that their "final expression is colored by culture, language and learning...
