Systematic testing of medical intractability for carbamazepine, phenytoin, and phenobarbital or primidone in monotherapy for patients considered for epilepsy surgery.

abstract：PURPOSE:Electrical stimulation (ES) is used during intracranial electroencephalography (EEG) investigations to delineate epileptogenic areas and seizure-onset zones (SOZs) by provoking afterdischarges (ADs) or patients' typical seizure. High frequency oscillations (HFOs--ripples, 80-250 Hz; fast ripples, 250-500 Hz) ar...
