| 摘 要： | 目的探讨内侧颞叶(MTL)在P300产生中的作用。方法对1例左颞叶切除的患者和17名健康对照者进行视、听两种模式下的P300研究。结果患者的视、听P300潜伏期(PL)、波幅(Amp)和侧性分布均在对照组确定的正常范围之内。结论一侧MTL结构切除并不影响事件相关电位的内源性成分P300，P300的产生可能是脑多个部位共同活动的电位综合。

| Abstract: | Objective To explore the role of medial temporal lobe (MTL) structure in generating P 300.Methods Event-related potentials (ERPs) were performed in the patient following left lateral anterior temporal lobectomy and 17 health subjects. Two models of vision and auditus were involved in the study.Results The latency, amplitude and sideway distribution of auditory and visual P 300 were in the normal range gained from the healthy controls.Conclusion MTL structure may be not important in generating scalp P 300. |
