Description: Personalised accounts of out-of-body (OBE) and near-death (NDE) experiences are frequently interpreted as offering evidence for immortality and an afterlife. Since most OBE/NDE follow severe curtailments of cerebral circulation with loss of consciousness, the agonal brain supposedly permits 'mind', 'soul' or 'consciousness' to escape neural control and provide glimpses of the afterlife. Michael Marsh critically analyses the work of five key writers who support this so-called "dying brain" hypothesis.
