We apply electrodes to the scalp to listen in on electrical activity also known as brainwave activity. We process the signal by computer, and we extract information about certain key brainwave characteristics. We show the ebb and flow of this activity back to the person, who attempts to change the activity level. Some frequencies we wish to promote. Others we wish to diminish. We present this information to the person in the form of a video game or video. The person is effectively playing the video game or controlling how well a video plays with his or her brain. Eventually the brainwave activity is “shaped” toward more desirable, more regulated performance. The frequencies we target, and the specific locations on the scalp where we listen in on the brain, are specific to the conditions we are trying to address, and specific to the individual. Neurofeedback sessions are usually at least twice a week to enhance efficient learning. The brain needs to practice over 40-60 sessions to effect lasting anatomical and physiological changes for most conditions.
