Slow Cortical Potentials Neurofeedback

Until recently, slow cortical potentials (SCP) training as a method of brainwave feedback has been widely ignored in the Anglo-American tradition of neurofeedback. One of the reasons was the lack of reliable and valid equipment outside a few research labs in Europe. In the meantime this has changed to the better. With devices now being available there is growing interest in SCP feedback. SCPs are very low shifts of brain activity. As they regulate excitation thresholds they may be used for self-regulation training in pathological conditions where excitation thresholds are impaired. This article explains technical requirements; describes training protocols; and gives a short overview on controlled research in epilepsy, attention deficit hyperactivity disorder, and migraine.
