Summary
Neurofeedback (NFB), also called neurotherapy or neurobiofeedback, is a type of biofeedback that uses realtime displays of electroencephalography (EEG) or hemoencephalography(HEG) to illustrate brain activity and teach self-regulation.
EEG neurofeedback uses sensors that are placed on the scalp to measure brain waves, while HEG neurofeedback uses infrared (IR) sensors or functional magnetic resonance imaging (fMRI) to measure brain blood flow.
