The physiology of the tunnel

Near-death experiences: reports, measurement and explanations

Some people who come close to death later report leaving their body, a tunnel, a bright light, meeting deceased relatives or a review of their life. This collection follows how psychology and medicine have studied these reports: from the first case collections (Moody, Ring) and the Greyson NDE Scale, through prospective studies of cardiac arrest survivors, to neurobiological, psychological and cultural explanations, distressing NDEs, and what changes in people's lives afterwards. What NDEs are is still debated, and the verdicts here are ours. Terms: * NDE: near-death experience * OBE: out-of-body experience * WCEI: Ring's Weighted Core Experience Index, an early measure of NDE depth
