When brain cells die they release glutamate which can stimulate other cells. When large numbers of cells die (as in cases where blood or oxygen can't reach the brain the volume of glutamate can cause other cells to die from over stimulation. In order to prevent this the brain will begin releaseing glutamate blockers which prevents more cells from dieing but also interferes with the normal functioning of the brain.

Ketamine, which is used as a vetranary anesthetic, is also a glutamate blocker and has been shown to produce near death experiences when administered to humans.

Thanks.

That was what I was looking for, an actual medical study.

Ketamine is well known for its ability to induce hullicinations and bad postop memories. I know it has been used for recreation for the former properties and I avoid it with children because of it latter. While I was active duty it was forbidden with rated officers in anesthesia and could potentially prevent them from getting back in the cockpit. I have no doubt that it could produce the "NDE" for the susceptible to suggestion.

I think we should always be skeptical - as long as we include being skeptical about being skeptical:)
