摘　　要：视皮层是大脑视觉信息的处理整合中心,灵长类动物的视皮层存在背侧和腹侧流2条相对独立而又相互联系的平行视觉信息通路。笔者总结了视皮层背侧通路(即where+how通路)、腹侧通路(即what通路)的发现、定位、功能以及二者的联系,并从视觉通路临床应用角度系统梳理了视觉皮层背侧、腹侧平行通路的研究进展。目前2条通路结构和功能相关性研究资料较少,对视皮层视觉通路的视觉信息分拣处理、相互作用及通路信息传递过程编码和神经整合处理机制尚缺乏深入研究。此外,关于2条通路的临床研究缺乏系统性和完整性,且研究结果分歧较大,今后需改进研究方法,加强深入研究视觉疾病视通路损害的结构和功能。本文通过对视皮层背侧通路、腹侧通路做—综述,以期为视觉信息的传递、加工和相关临床眼病防治研究提供理论基础。The visual cortex,which is the center for processing and integrating the visual information,exists two distinct and separate visual systems in primate visual cortex-dorsal pathway(also know as where and how pathway)and ventral pathway(also know as what pathway).In this review,we present the discovery,localization,function and relationship of the two pathways,and review the recent advances in methodology and clinical trials-related two pathways as well.Existing literature show that there is little research on the correlation of the two pathways'structure and function,and lack of in-depth mechanism studies on the interaction between dorsal and ventral pathways.In addition,the result of clinical trials are not quite similar.So the clinical trial designs should improved and more further research is needed and necessary to provide the basis for the projecting and processing of visual information in visual cortex,and to prevent and treat eye disorders in future.
