Right hemisphere dominance for visuospatial attention is characteristic of most humans, but its anatomical basis remains unknown. We report the first evidence in humans for a larger parieto-frontal network in the right than left hemisphere, and a significant correlation between the degree of anatomical lateralization and asymmetry of performance on visuospatial tasks. Our results suggest that hemispheric specialization is associated with an unbalanced speed of visuospatial processing.
右半球对视觉空间注意力的主导作用是大多数人的特征，但它的解剖学基础仍然未知。我们报告了人类第一个右半球比左半球具有更大的顶-额网络的证据，以及解剖侧化程度与视觉空间任务表现的不对称性之间的显著相关性。我们的结果表明，半球专门化与视觉空间处理速度的不平衡有关。
