A system and method for applying electrical stimulation or drug infusion to nervous tissue of a patient to treat epilepsy, movement disorders, and other indications uses at least one implantable system control unit (SCU) ( 110 ), including an implantable signal/pulse generator (IPG) and one or more electrodes ( 152, 152 ′). The IPG is implanted in the mastoid area ( 143 ) of the skull ( 140 ) and communicates with at least one external appliance ( 230 ), such as a Behind-the-Ear (BTE) unit ( 100 ). In a preferred embodiment, the system is capable of open- and closed-loop operation. In closed-loop operation, at least one SCU includes a sensor, and the sensed condition is used to adjust stimulation parameters. |
