I don't remember the original thread, but Ritu had mentioned a study in which near-death experiences were surveyed; here is one article about that:
http://abcnews.go.com/sections/GMA/DrJohnson/GMA020108Near_death_experiences.html "...The study reported in Lancet looked at 344 patients in the Netherlands who were successfully resuscitated after suffering cardiac arrest in 10 Dutch hospitals. "Rather than using data from people reporting past near-death experiences, researchers talked to patients within a week after they had suffered clinical deaths and been resuscitated. (Clincical death was defined as a period of unconsciousness caused by insufficient blood supply to the brain.) "About 18 percent of the patients in the study reported being able to recall some portion of what happened when they were clinically dead; and 8 to 12 percent reported going through "near-death" experiences, such as seeing lights at the end of tunnels, or being able to speak to dead relatives or friends. Most had excellent recall of the events, which undermines the theory that the memories are false, the study said..." The euphoria some experience probably is related to endorphin/enkephalin release, but the recall of events when there isn't any blood flow to the brain *is* puzzling. "...Blackmore says science can also explain those tunnels: Electrical brain scans show that in our last moments, as the brain is deprived of oxygen, cells fire frantically and at random in the part of the brain which govern vision. "Now, imagine that you've got lots and lots of cells firing in the middle, towards fewer at the outside, what's it going to look like? Bright light in the middle fading off towards dark at the outside," Blackmore said. "I think that's where the tunnel comes from. And as the oxygen level drops, so the bright light becomes bigger and more immediate, and you get this sensation of rushing forward into the light." ..." <grin> Of course, that means you must imagine that instead of the documented *random* neuron firing, you are positing *coordinated* neuron firing...In my own near-drowning, I saw sparkly lights against a dark-grey background, which is consistant with a random-fire pattern Here is the paper abstract: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11755611&dopt=Abstract "...We do not know why so few cardiac patients report NDE after CPR, although age plays a part. With a purely physiological explanation such as cerebral anoxia for the experience, most patients who have been clinically dead should report one."
