Abstract
Event-related potentials (ERP) were recorded during auditory oddball t asks for a patient prior to and soon after left anterior temporal lobe ctomy. The N100 amplitude decreased bilaterally although the latency d id not change after the lobectomy. The P300 amplitude decreased in the left hemisphere at 1 and 2 weeks after surgery, then recovered to the pre-operative level at 4 weeks. These findings suggest that the media l temporal structure participates in the generating system of P300.
