<unk>  (HEG) is a neurofeedback technique in the field of neurotherapy. Neurofeedback, a specific form of biofeedback, is based on the idea that human beings can consciously alter their brain function through training sessions in which they attempt to change the signal generated by their brain and measured via a neurological feedback mechanism. On completion of the process, participants increase cerebral blood flow to a specified region of the brain, consequently increasing brain activity and performance on tasks involving the specific region of the brain.
