The dorsal premotor cortex is a functionally distinct cortical field or group of fields in the primate frontal cortex. Anatomical studies have confirmed that most parietal input to the dorsal premotor cortex originates from the superior parietal lobule. However, these projections arise not only from the dorsal aspect of area 5, as has long been known, but also from newly defined areas of posterior parietal cortex, which are directly connected with the extrastriate visual cortex. Thus, the dorsal premotor cortex receives much more direct visual input than previously accepted. It appears that this fronto-parietal network functions as a visuomotor controller-one that makes computations based on proprioceptive, visual, gaze, attentional, and other information to produce an output that reflects the selection, preparation, and execution of movements.
背侧运动前区皮质是灵长类动物额叶皮质中一个功能独特的皮质区或一组皮质区。解剖学研究证实，背侧运动前区皮质的大部分顶叶输入起源于顶上小叶。然而，这些投射不仅如长期以来所知的那样来自5区的背侧，还来自后顶叶皮质的新定义区域，这些区域与纹外视觉皮质直接相连。因此，背侧运动前区皮质接收的直接视觉输入比以前认为的要多得多。看来，这个额顶叶网络起着视觉运动控制器的作用——它根据本体感觉、视觉、注视、注意力和其他信息进行计算，以产生反映运动选择、准备和执行的输出。
