Neurofeedback, also called EEG Biofeedback, is a self regulation training tool that enables a person to alter his or her brain waves (EEG). When information about a person’s own brain wave patterns are made available to him, he can learn to change them. You can think of it as operant conditioning of the brainwaves and as exercise for the brain.
This Youtube video gives a good overview to neurofeedback:
Neurofeedback is used for many conditions in which the brain is not operating as efficiently as it could. These can include ADHD and more severe conduct problems, specific learning disabilities, sleep problems, and chronic pain problems including migraine. The training is also helpful with the control of mood disorders such as anxiety and depression, as well as for more severe conditions such as PTSD and Developmental Trauma.
Before neurofeedback training begins, the therapist will ask the client for a thorough description of his or her symptoms, health history and family history and several baseline EEG measurements will be taken in order to determine the best training approach. In most instances, clients will train at least once a week. Training sessions may be anywhere from 15 to 45 minutes in duration. It is not unusual to see improvement within the first 20 sessions. Neurofeedback is a learning process. Once this learning is consolidated, its benefits are generally long-lasting and usually enduring.
The EEG biofeedback training is a painless, non-invasive procedure. One or more sensors are placed on the scalp, and one to the ear, using a salt-based conductive paste. The brain waves are monitored by an amplifier and a computer-based instrument that processes the signal and reflects it back to the trainee in the form of video game or other video display. The trainee is asked to play the video game by making changes is his/her EEG pattern. As the person’s EEG activity shifts into a more efficient pattern, the trainee will receive information that she has done so through auditory and visual feedback in the video game.
The trainer has set frequency bands to increase in amplitude (rewards) and others to decrease in amplitude (inhibits). As activity in a desirable frequency band increases, the trainee will receive information that she has done so through auditory and visual feedback in the video game. If EEG activity either does not change or becomes inefficient, the video game is inhibited. Gradually, the brain responds to the cues that it is being given, and learns new brain wave patterns. We assess progress through changes in symptoms, behaviors, and EEG recordings.
