Jimo Borjigin, a professor of neurology at the University of Michigan ... took the first close look at the record of electrical activity in the brain of Patient One after she was taken off life support. After Patient One was taken off oxygen, there was a surge of activity in her dying brain. Areas that had been nearly silent while she was on life support suddenly thrummed with high-frequency electrical signals called gamma waves. In particular, the parts of the brain that scientists consider a "hot zone" for consciousness became dramatically alive. Since the 1960s, advances in resuscitation had helped to revive thousands of people who might otherwise have died. About 10% or 20% of those people brought with them stories of near-death experiences in which they felt their souls or selves departing from their bodies. According to several international surveys and studies, one in 10 people claims to have had a near-death experience involving cardiac arrest, or a similar experience in circumstances where they may have come close to death. That's roughly 800 million souls worldwide who may have dipped a toe in the afterlife. If there is consciousness without brain activity, then consciousness must dwell somewhere beyond the brain. Parapsychologists point to a number of rare but astounding cases. One of the most famous is about a woman who apparently travelled so far outside her body that she was able to spot a shoe on a window ledge in another part of the hospital where she went into cardiac arrest; the shoe was later reportedly found by a nurse.
