There is increasing demand for neurofeedback as part of treatment for disorders with known neurobiological correlates, and thus for some psychiatric and neurological clinical pictures as well (including ADHD, autism, migraine, epilepsy). This volume provides sound theoretical and technical foundations on neurofeedback and fields of application for it. It describes both the scientific evidence and practical procedures related to individual clinical pictures. This second edition has been completely revised and expanded with chapters on psychopathy and post-traumatic stress disorder.
