Does the corpus callosum have a significant relationship with motor memories/ muscle memories?
This study tests the time it takes for patients with damaged corpus callosums to perform intermanual transfer motor tasks.
Patients drew a meaningless figure with one hand, then did it again with the other hand (And vice versa). Thus performing intermanual transfer.

All three patients displayed a significant benefit for transfer from the dominant to the non-dominant hand but not vice versa during proximal motor activity.


...the proximal transfer behavior was found to be similar for all patients in the healthy group.

From these results, a relationship exsists.
