Near-death experiences explained ?

Scientists believe a surge of electrical activity in the brain could explain the NDE phenomenon. People who have been on the brink of death or who have died and been resuscitated have often described unusual experiences that include seeing a tunnel of light, the sensation of floating above one's own body or the feeling of a divine presence. Some attribute these experiences to the passage between this life and the next, but scientists believe there may be a more down-to-earth explanation.

 In a new study, researchers discovered that electrical activity in the brain could account for the vivid experiences some people describe. "A lot of people thought that the brain after clinical death was inactive or hypoactive, with less activity than the waking state, and we show that is definitely not the case," said study lead author Dr Jimo Borjigin.

 "If anything, it is much more active during the dying process than even the waking state." A surge of electrical activity in the brain could be responsible for the vivid experiences described by near-death survivors, scientists report.
