刺激重复可提高单词识别任务的表现并调节与事件相关的脑电位。我们记录了大脑双侧颞叶的诱发磁反应，以确定与单词重复效应相关的皮层区域。14名日本志愿者阅读单词或可发音的非单词，其中一些出现了两次，延迟了8个项目。双侧观察到明显的磁反应。在刺激后300-500 ms的潜伏期范围内，左半球通过重复观察到单词的磁反应减少，而非单词的磁反应没有减少。据估计，这些反应的来源位于与听觉皮层和左顶叶区相邻的左耳廓区。只有perisylvian源活动表现出单词重复的减少。因此，我们认为左periisylvian区域与单词重复效应有关。这个区域的活动可能与词汇记忆过程有关。
Stimulus repetition improves performance and modulates event-related brain potentials in word recognition tasks. We recorded evoked magnetic responses from bilateral temporal sites of the brain to determine the cortical area related to the word repetition effect. Fourteen Japanese volunteers read words or pronounceable nonwords, some of which occurred twice with a lag of eight items. Clear magnetic responses were observed bilaterally. In the left hemisphere, a reduction of the magnetic responses by repetition was observed for words but not for nonwords in the latency range of 300-500 ms poststimulus. The sources of the responses were estimated to be in the left perisylvian area adjacent to the auditory cortex and the left parietal area. Only the perisylvian source activity showed the reduction by the word repetition. The left perisylvian area was thus suggested to be related to the word repetition effect. The activity in this area might be associated with the lexical memory process.
