Neurofeedback, also known as EEG (electroencephalogram) biofeedback, is a  therapeutic intervention that provides immediate feedback from a  computer-based program that assesses a client’s brainwave activity. The  program uses auditory or visual signals to help patients recognize their  thought patterns and try to modify them. Through this process, clients  can learn to regulate and improve their brain function and hopefully  alleviate symptoms of various neurological disorders and mental health  conditions.
