According to recent conceptualizations, there are two separate cortical visual systems--each with its own distinctive cortical and subcortical links--and these two systems respectively serve the functions of perception and of motor control. These ideas have been arrived at through a confluence of neuroanatomical, electrophysiological, behavioural, and neuropsychological research. It is proposed that this distinction between two broad purposes of vision and their neural bases can provide useful working procedures for analysing both: (i) the nature of visuomotor processing in the normal brain; and also (ii) the abnormal patterns of visual processing that are seen in certain neurological conditions.
根据最近的概念，存在两个独立的皮质视觉系统——每个系统都有其独特的皮质和皮质下联系——这两个系统分别执行感知和运动控制功能。这些观点是通过神经解剖学、电生理学、行为学和神经心理学研究的融合得出的。有人提出，视觉这两个广泛目的与其神经基础之间的这种区别，可为分析以下两方面提供有用的工作程序：(i) 正常大脑中视觉运动处理的性质；以及 (ii) 在某些神经疾病中出现的视觉处理异常模式。
