Neurofeedback

Neurofeedback (NFB), also called neurotherapy, neurobiofeedback or EEG biofeedback is a type of biofeedback that uses realtime displays of electroencephalography or functional magnetic resonance imaging (fMRI) to illustrate brain activity, often with a goal of controlling central nervous system activity. Sensors are placed on the scalp to measure activity, with measurements displayed using video displays or sound.
