Abstract

Similar to the visual dual-pathway model, neurophysiological studies in non-human primates have suggested that the dual-pathway model is also applicable for explaining auditory cortical processing, including the ventral “what” pathway for object identification and the dorsal “where” pathway for spatial localization. This review summarizes evidence from human neuroimaging studies supporting the dual-pathway model for auditory cortical processing in humans.

听觉信号加工的双通路模型

摘要

神经电生理学研究发现, 处理视觉信息的人大脑皮层的双通路模型概念也适用于非人灵长类动物大脑皮层听觉信息的加工, 即存在一条识别物体特征的腹侧通路和一条加工空间信息的背侧通路。本文系统地总结了近年来有关人类听觉加工的脑成像研究, 并根据这些实验结果对人听觉双通路的加工理论模型进行了讨论。
