MULTI-CHANNEL TRANSDERMAL STIMULATION OF THE BRAIN

Abstract

A system was developed for multichannel electrical stimulation of the brain through the intact skin. The stimulator which is implanted subcutaneously, has no batteries and may be used for the lifetime of the experimental subject. Power and information are provided by a small pack carried externally and activated by radio (100 MHz). A combination pulse width and frequency modulation technique is employed to encode the signal information. Three channels are available and in each, repetition rate, pulse durations, and intensity are remotely controlled, allowing the adjustment of parameters of brain stimulation in completely unrestricted subjects.
