Neurofeedback is direct training of brain function, by which the brain learns to function more efficiently. The brain is observed in action from moment to moment then show that information back to the patient, and reward the brain for changing its own activity to more appropriate patterns.

Neurofeedback is also called EEG Biofeedback, because it is based on electrical brain activity, the electroencephalogram, or EEG. This gradual learning process applies to any measurable aspect of the brain.
