How is Neurofeedback Done?

During the session, the child, adolescent or adult sits in a comfortable chair, typically for about 30-45 minutes. Two or more leads or sensors are attached to the scalp with a water-soluble paste; brainwave signals are then able to be detected and sent to a computer using special software and hardware that amplifies the signals. The computer displays interesting graphics in the form of a game or a movie (visual feedback) and your brainwaves control the progress of the visual information being seen. As brain waves are generated which represent well-regulated attention and arousal levels, the visual graphics continue uninterrupted. Large excursions in optimal brain wave activity will cause the graphics to either stop or change in their quality. The brain then responds to the challenge of the feedback and moves towards more adaptive and flexible functioning. The therapist is responsible for making the necessary changes in the placement of the sensors and management of the raw EEG data being obtained.
