A method of selectively inhibiting or driving neural discharge or activity in or from a specific brain area of a mammal by means of a signal unit means having a CPU processor and signal generator, a surface cortical electrode having a stimulation portion, and a connecting lead, having a proximal end coupled to the signal generator means and a distal portion comprising the electrode; the method comprising (a) locating the stimulation portion of the electrode within the brain parenchyma or adjacent the surface of the brain; (b) coupling the lead to the signal unit means; (c) detecting the pathological intrinsic neural discharges or activity with the electrode to generate a sensor signal within the electrode; (d) analyzing the sensor signal by the signal unit; and (e) prescribing and generating timely electrical pulse stimuli with the signal unit and delivering the impulses to the electrode to alter, block, augment or modify the consequences of the intrinsic neural discharge or activity; wherein the timed pulses are delivered at a time selected from the group consisting of preceding, coinciding with and following said neural discharge or activity. The method and apparatus provides for an improved treatment of neurological disorders particularly movement disorders, such as Parkinson's disease, psychiatric diseases, such as depression, chronic pain disorders, such as post-neural injury pain, and epilepsy, in mammals by electrical stimulation of the brain.
