Neurofeedback is a technique for teaching the brain to alter its responses to the outside environment. EEG (electroencephalograph) or simply "brainwaves" are the electrical impulses that the brain continuously creates. The sort of brainwaves that a person produces impacts how he or she thinks and acts. When a person suffers from obsessive-compulsive disorder (OCD), for example, they may experience acute anxiety in circumstances that other people would not find disturbing. When an individual plays a game, watches a movie, or listens to music, a computer monitors the individual's brain waves.This is how you can retrain your brain from OCD.
