Imagine a procedure versatile enough to treat epilepsy, autism, attention deficit disorder, addictions, and depression with no drugs or side effects; to bring patients out of vegetative states; and to improve everything from golf scores to opera singers' voices. These are only some of the claims made for neurofeedback, a controversial but effective treatment that is revolutionizing the way an incredibly diverse range of medical and psychological conditions are treated. In A Symphony in the Brain, Jim Robbins traces the fascinating, untold story of the development of neurofeedback, from its discovery by a small corps of research psychologists, to its growing application across the country and around the world, to present battles for acceptance in the conservative medical world. Offering a wealth of powerful case studies, accessible scientific explanations, and dramatic personal accounts, Robbins journeys through a remarkable field, which he brings to the public eye for the first time.
