Intrigued as I am with the neurophysiology of nirvana, I was very disappointed to discover recently that the researchers who say they can stimulate mystical experiences or religious visions by situating a bank of magnets on your head may not in fact be able to deliver the spiritual goods.* As much as I wish it did, the God Helmet, it seems, doesn't really work. First my friend Nick weighed in, having researched the topic in detail for a documentary he's doing about the origins of yoga, which includes interviews with various scientists who have tried to montior or measure or locate where exactly in the brain the Oneness with the Universe resides. The result, according to Nick: no one yet knows. The science is still fuzzy. And then came a a recent piece in Nature noting that the results from the original God Helmet team haven't been replicated by a team running the same experiment in Sweden. Shucks. I was hoping to sit in the chair myself one of these days and dive into that eloctromagnetically-generated existential ocean.
* I recommend this link nevertheless; it's s a long personal investigation into the God Helmet by Jack Hitt.
