Neurofeedback (also called EEG-biofeedback) is a direct training of brain function by which the brain learns to function more efficiently. Sophisticated electronic devices monitor and feedback information to the client about minute changes in EEG patterns and relationships. This is a training approach and not a therapeutic intervention. Nothing is done to the client, there is no electrical input into the client and the neurofeedback device is simply measuring the scalp surface electrical activity in a way that is similar to a doctor listening to a heartbeat from the skin surface using a stethoscope.
The client interacts with himself through the medium of the feedback. Any changes in physiological activity are recorded and reflected back to the individual through the use of computer displays and audio tones that change from moment to moment. Using this information, the client can experiment with various techniques of self-awareness, insight, mental practice and relaxation while observing instantaneous responses from the computerized feedback.
This process of feeding back information and rewarding the brain for changing to more appropriate patterns facilitates the training experience, making it much more accurate and consistent and also reduces the time necessary for learning to occur.
Neurofeedback is training in self-regulation. Self-regulation is a necessary part of good brain function. Self-regulation training allows the central nervous system to function better.
Neurofeedback addresses problems of brain dysregulation. These happen to be numerous. They include the anxiety-depression spectrum, attention deficits, behaviour disorders, various sleep disorders, headaches and migraines, PMS and emotional disturbances, depression and fatigue. It is also useful for organic brain conditions such as seizures, PTSD, TBI, the autism spectrum, and cerebral palsy.
