本研究通过在人听皮层（Heschl 'sgyrus和temporalale）内记录中潜伏期听觉诱发电位（MLAEPs），确定并定位MLAEPs各成分的发生源，结果表明：潜伏期30、50、60和75 ms的成分发生源沿Heschl' sgyrus分布于沿着。30毫秒分量产生于Heschl回的背后内侧部分（主要区域），50毫秒分量产生于主要区域的外侧。后一成分（60-75毫秒）的发生器位于构成次级区的Heschl回外侧部，并对N100发生器的定位进行了讨论。
The goal of this study is to determine and localize the generators of different components of middle latency auditory evoked potentials (MLAEPs) through intracerebral recording in auditory cortex in man (Heschl's gyrus and planum temporale).The present results show that the generators of components at 30, 50, 60 and 75 msec latency are distributed medio-laterally along Heschl's gyrus. The 30 msec component is generated in the dorso-postero-medial part of Heschl's gyrus (primary area) and the 50 msec component is generated laterally in the primary area. The generators of the later components (60-75 msec) are localized in the lateral part of Heschl's gyrus that forms the secondary areas.The localization of N100 generators is discussed.
