Imagine a simple procedure versatile enough to treat epilepsy, autism, attention-deficit disorder, addictions, and depression with no drugs, surgery, or side effects, and to improve everything from golf scores to sleep to opera singers' voices. These are only some of the capabilities of neurofeedback, a controversial but effective treatment that is growing rapidly in use around the world and is revolutionizing the way an incredibly diverse range of medical and psychological conditions are treated. For more than twenty years a small handful of neurofeedback practitioners have achieved dramatic results in thousands of cases. Using computerized biofeedback equipment and capitalizing on recent scientific research that illustrates the profound plasticity of the brain, clinicians train patients to function in brain frequencies they don't usually use. This exercise strengthens the brain and the rest of the nervous system, with powerful effects on the entire body. Yet, because of the unusual nature of the procedure and the boldness of their claims, proponents of neurofeedback have found it nearly impossible to convince the medical field to take the treatment seriously. This situation, however, is changing. 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 scientists to its growing application across the country and around the world, to the contentious history of biofeedback in the 1970s, to present battles for acceptance in the medical and psychological community. He builds a compelling argument for research funding for neurotherapy and shows how almost anyone can gain from the technique. 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.
