Event-related potentials (ERP) were recorded during auditory oddball tasks for a patient prior to and soon after left anterior temporal lobectomy. The N100 amplitude decreased bilaterally although the latency did 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 medial temporal structure participates in the generating system of P300.
在左侧颞叶前部切除术之前及术后不久，对一名患者在听觉Oddball任务期间记录了事件相关电位（ERP）。尽管潜伏期在叶切除术后没有变化，但双侧N100波幅降低。术后1周和2周时，左侧半球P300波幅降低，然后在4周时恢复到术前水平。这些发现提示内侧颞叶结构参与P300的产生系统。
