One of the subjects that has both captivated and eluded humankind throughout time is the mystery of what happens when we die. Although traditionally a subject for philosophical or theological debate, scientific progress has begun to shed light on both the physiological as well as cognitive processes such as near death experiences that take place during clinical death. Dr. Sam Parnia, author of What Happens When We Die, chronicles the history and development of the study of cardiac arrest as well as near death experiences. At the same time, he will introduce the novel method he and his colleagues have devised to study the phenomenon of consciousness and the human mind at the end of life, which they hope will finally enable science to resolve the mystery of near death experiences. http://www.gold.ac.uk/apru/lectures and http://skeptic.org.uk/archive
