An electrode-preferably an anode (current sink)-is implanted within a ventricle of the brain so that the cerebrospinal fluid therein, which is highly conductive, effectively makes the ventricle a conductive extension of the anode. An opposing electrode (i.e., a cathode) can then be situated within or outside the brain (e.g., extradurally) so that a portion of the brain to be electrically stimulated is situated between the electrodes. The electrodes can then be energized at appropriate frequencies and current/voltage levels to apply the desired stimulation, in a manner similar to preexisting Deep Brain Stimulation (DBS), Extradural Motor Cortex Stimulation (EMCS), and other electrical brain stimulation procedures.
