  • Title: Interhemispheric control of manual motor activity.
    Author: Geffen GM, Jones DL, Geffen LB.
    Journal: Behav Brain Res; 1994 Oct 20; 64(1-2):131-40. PubMed ID: 7840879.
    Abstract:
    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 asychronous bimanual movements and to inhibit the opposite hemisphere from interfering when a simple unimanual movement is required.
