Abstract
Abstract Techniques for stimulating the brain to treat movement disorders resulting in abnormal motor behavior by means of an implantable signal generator and electrode. A sensor is used to detect the symptoms resulting from the motion disorder. A microprocessor algorithm analyzes the output from the sensor in order to regulate the stimulation delivered to the brain.
