人们普遍认为，右侧后顶叶皮层在视觉空间和定向注意力中起着重要作用。许多证据表明，虽然定向和动眼肌反应的准备是相互分离的，但两者是密切相关的。如果这是真的，那么就有可能确定与其他反应模式相关的其他注意机制。我们使用重复经颅磁刺激（rTMS）来证明存在一个独特的运动注意的前顶叶机制。运动注意的关键区域位于与定向有关的区域的前部，并且在人类的左半球偏侧。
It is widely agreed that the right posterior parietal cortex has a preeminent role in visuospatial and orienting attention. A number of lines of evidence suggest that although orienting and the preparation of oculomotor responses are dissociable from each other, the two are intimately related. If this is true, then it should be possible to identify other attentional mechanisms tied to other response modalities. We used repetitive transcranial magnetic stimulation (rTMS) to demonstrate the existence of a distinct anterior parietal mechanism of motor attention. The critical area for motor attention is anterior to the one concerned with orienting, and it is lateralized to the left hemisphere in humans.
