视听整合加工及其神经机制

通常人们接收到来自不同感觉通道的信息时, 首先在大脑中各个分离的区域单独进行加工处理, 而后在多感官区进行整合。前人关于言语感知中视听整合加工的神经成像研究认为, 视觉和听觉信息能够相互影响; 两者进行整合的关键区域是人脑左后侧的颞上沟, 其整合效应受时间和空间因素的限制。未来的研究应致力于建立更加合理的实验范式和数据分析方法来探讨整合加工的脑区机制, 把多感官整合研究进一步延伸到更加复杂的领域。

Processing of Audiovisual Integration and Its Neural Mechanism

Incoming signals from different sensory modalities are initially processed in anatomically separate regions in human brain, and then be integrated in multimodal association cortices. From human imaging studies about audiovisual integration in speech perception it is clear that auditory and visual inputs can influence each other and be integrated primarily in the left posterior superior temporal sulcus (STS). Increasingly, this integrative effect should be constrainted by space and time. Further trends will ...
