Pain can be felt anywhere in the body, but it all originates in the same place: the brain. Lorimer Moseley, a professor of clinical neurosciences at the University of South Australia and a specialist in how the brain produces pain signals, joins us today to talk about how pain is created as a protective strategy. Your brain, which is constantly monitoring your environment for signs of danger vs safety, sends pain signals when it detects a painful stimulus (a process called nociception).  Moseley studies how to retrain the brain when it continues to send pain signals long after the damaged tissue has healed (or, in the case of phantom pain, even after the damaged tissue is gone).  Plus - the dangers of a pain-free life.
