The dorsal and ventral premotor areas, together with the primary motor cortex, are believed to have major roles in preparing and executing limb movements. Recent studies have expanded our knowledge of the dorsal and ventral premotor areas, which occupy the lateral part of area 6 in the frontal cortex. It is becoming clear that these two premotor areas, through involvement in distinct cortical networks, take part in unique aspects of motor planning and decision making. New lines of evidence also implicate the lateral premotor areas in planning motor behavior and selecting actions.
背侧和腹侧运动前区与初级运动皮层一起，被认为在准备和执行肢体运动中起主要作用。最近的研究扩展了我们对背侧和腹侧运动前区的认识，这两个区域位于额叶皮层6区的外侧部分。越来越清楚的是，这两个运动前区通过参与不同的皮层网络，参与运动规划和决策的独特方面。新的证据线索也表明外侧运动前区参与运动行为的规划和动作的选择。
