Introduction  It is now generally assumed that psychomotor epilepsy is of temporal lobe origin, although psychomotor phenomena may occur in association with discharges arising in areas quite remote from the temporal lobe. In fact, because the phenomenology of psychomotor epilepsy includes practically all of the possible cerebral functions—somatic, visceral, and psychic—one would doubt, a priori, the constant origin of such discharges from one source. It therefore becomes particularly pertinent, in patients being considered for temporal lobectomy, to demonstrate that psychomotor phenomena are of temporal origin before an excision of the lobe is advised.The series reported here consisted of 14 patients, having medicinally uncontrollable psychomotor epilepsy, who were referred for consideration of surgical intervention. Because the seizures or electroencephalographic findings were atypical, it was considered advisable to study in some detail the activity of the brain in areas somewhat removed from the temporal lobe by means of depth electrodes.
