| 摘 要： | 目的:探讨触觉-视觉交叉模式工作记忆的大脑神经活动机理.方法:训练11个正常受试者学习交叉模式工作记忆任务,利用Neuroscan EEG系统记录脑电活动,对脑电数据求源分析后,着重考察事件相关脑电成分所处的大脑空间位置.结果发现:在延时过程中的3个主要的脑电成分N40,LPC和LNC的神经活动源分别处于大脑的右侧顶叶,中间后顶叶和前额叶.这提示了交叉模式工作记忆中相继的三个神经认知功能:感知,触觉一视觉模式阃的信息交互,和工作记忆的维持.

| Abstract: | To investigate neural mechanisms of tactile-visual corssmodal working memory,we trained eleven subjects to learn the delayed match-tosample crossmodal working memory tasks,and recorded scalp EEG (electroencephalography).By applying ERP topography analysis to these subjects,we found that during the delay period,the three ERP components(N40,LPC,and LNC) were located in the right parietal area,the center posterior parietal area and the frontal area,respectively.The results indicated the sequential neural proce... |
