Abstract

A fundamental question in visual perception is whether the representation of the fovea is split at the midline between the two hemispheres, or bilaterally represented by overlapping projections of the fovea in each hemisphere. Here we examine psychophysical, anatomical, neuropsychological and brain stimulation experiments that have addressed this question, and argue for a shift from the current default view of bilateral representation to that of a split representation, to provide a greater understanding of higher visual processes.

摘要

视觉感知中的一个基本问题是,中央凹的表征在两个半球之间的中线处是否是分开的,还是由每个半球中中央凹的重叠投射进行双侧表征。在这里,我们研究了针对这个问题的心理物理学、解剖学、神经心理学和脑刺激实验,并主张从当前默认的双侧表征观点转向分开表征的观点,以更深入地理解高级视觉过程。
