Cortical Stimulation Surgery

О процедуре Cortical Stimulation Surgery

Cortical stimulation surgery involves placing electrodes directly on or just beneath the surface of the brain's outer layer, the cerebral cortex, to deliver controlled electrical impulses that can either modify abnormal activity or help map brain function during other procedures. In chronic pain management, electrodes are positioned over the motor cortex and connected to an implanted pulse generator to help reduce certain treatment-resistant pain conditions by altering how pain signals are processed. In epilepsy care, temporary cortical electrode grids are sometimes placed during a separate procedure to precisely map areas responsible for movement, sensation, or language before planning tumor or seizure-focus removal, reducing the risk of damaging essential brain function. Candidates for cortical stimulation are usually selected after other treatments have failed to provide adequate relief, and the decision involves careful assessment by a specialist team along with imaging to confirm accurate electrode placement. Recovery depends on the specific indication, with permanent implants requiring a period of adjustment and follow-up programming. India's neurosurgical centres performing this procedure combine intraoperative neuromonitoring with experienced surgical teams, supporting both diagnostic mapping and longer-term stimulation therapy for appropriately selected patients.
