MONITORING DURING SUPRATENTORIAL SURGERY

Summary: Electroneurophysiological monitoring is employed during vario us supratentorial surgical procedures. EEG and evoked potential monito ring are used to detect and to facilitate the timely correction of cer ebral ischemia during carotid endarterectomy and aneurysm surgery. Dir ect cortical recording and stimulation is used to identify areas or co rtex that would be likely to produce clinical deficits if removed. Ele ctrocorticography is used to identify epileptogenic cortex intraoperat ively during surgical treatment of epilepsy.
