Devices that apply stimuli to specific areas of a patient\'s brain (e.g., cerebrum, cerebellum) to prevent or alleviate seizures. Antiseizure brain stimulators may consist of an implanted lead/electrode system (attached to a passive electronic circuit into which energy and/or signals are inductively coupled from outside the body, typically at radio frequencies) or a totally implantable self-contained stimulator (that carries its own energy source and has no inherent dependence upon external devices, except for activation or change of stimulation settings). These stimulators are used to treat epilepsy and/or convulsive and movement disorders (e.g., cerebral palsy).
