Melvyn Bragg and guests discuss pain; something of which everyone has an individual experience. What causes it, how do we cope with it, what mechanisms are involved, what is the traditional view of pain and how is that being challenged today? Do we experience pain in the same way and how is emotional pain different from physical pain? What can our experience of pain tell us about ourselves and human consciousness? Is each individual human experience unique or are there experiences we can say apply across all of human consciousness? Is science a blunt instrument for examining subjective experience?With Patrick Wall, Professor of Physiology at St Thomas’ Hospital, London and author of Pain: The Science of Suffering; Semir Zeki, Professor of Neurobiology at University College, London.
