Chronic cortical electrode array for seizure investigation.
Localization of seizure focus if surgical extirpation is contemplated is critical. It is routine to use cortical recording and stimulation for this purpose but the limited time available in the operating room limits what can be learned. We report a flexible electrode array of four 0.05 disc which can be banked to larger sizes, and left in place subdurally as well as epidurally. It can be used for stimulation as well as recording.
