纵裂控制的手动运动过程进行审查，重点是从连合切开术和胼胝体发育不全的患者的临床证据。很少有证据表明胼胝体在传递外显运动指令中的作用。相反，胼胝体似乎对传递前运动的侧化信息（如言语或视觉空间活动）很重要。品种此外，当运动开始时，胼胝体可能变得非常重要：似乎有一个必然的运动信号和反馈感觉信号的经胼胝体通道，用于控制异步双手运动，并在需要简单的单手运动时抑制对侧半球的干扰。
The interhemispheric control of manual motor processes is reviewed, focusing on the clinical evidence from patients with commissurotomies and with agenesis of the corpus callosum. There is little evidence for a role of the corpus callosum in transferring explicit motor commands. Rather, the corpus callosum seems important for transferring lateralised information (such as verbal or visuospatial activity) of the pre-motor. variety. Also, the corpus callosum may become very significant when movement begins: there appears to be a transcallosal passage of corollary motor signals and feedback sensory signals that are used to control asynchronous bimanual movements and to inhibit the opposite hemisphere from interfering when a simple unimanual movement is required.
