The Scientific Explanations Behind Near-Death ExperiencesS

The light at the end of the tunnel. An out-of-body experience. Your life flashing before your eyes. According to Scientific American's Charles Q. Choi, 3% of Americans have had a near-death experience; now scientists are beginning to unravel the biological roots of these experiences.

Choi writes:

Near-death experiences are often thought of as mystical phenomena, but research is now revealing scientific explanations for virtually all of their common features.

...Recently, a host of studies has revealed potential underpinnings for all the elements of such experiences. "Many of the phenomena associated with near-death experiences can be biologically explained," says neuroscientist Dean Mobbs, at the University of Cambridge's Medical Research Council Cognition and Brain Sciences Unit.
