The neural mechanisms of limb coordination were investigated by testing callosotomy patients and normal control subjects on bimanual movements Normal produced deviations in the trajectories when spatial demands for two hands different, despite temporal synchrony onset Callosotomy did not produce deviations, although their moved with but exhibited large increases planning execution time different relative to identical This dissociation indicates that interference results from callosal connections, whereas movement does rely corpus callosum
