Visuomanual co-ordination requires the merging of ocular and arm information in a common frame of reference. Here we consider behavioural evidence in humans for the use of a viewer-centred frame in the specification of end point positions of reaching. We then review anatomical and neurophysiological data in the non-human primate that indicate a prominent role of the parietal cortex in the process of multisensory fusion that leads to egocentric representations of space. Finally, we discuss the functional anatomy of the human parietal cortex in visuomanual co-ordination as revealed by neuroimaging.
视觉手动协调需要在一个共同的参照系中整合眼部和手臂的信息。在这里,我们考虑人类行为证据,以说明在确定伸手可及终点位置时使用以观察者为中心的参照系。然后,我们回顾了非人类灵长类动物的解剖学和神经生理学数据,这些数据表明顶叶皮质在多感官融合过程中起着重要作用,该过程导致以自我为中心的空间表征。最后,我们讨论了神经成像所揭示的人类顶叶皮质在视觉手动协调中的功能解剖结构。
