Does the corpus callosum have a significant relationship with motor memories/ muscle memories?

Biology Asked by AgentMFaith on August 24, 2020

With the corpus callosum located in the cerebrum, and motor memories having a closer relationship to the cerebellum (which I’m not quite sure about), is there a significant relationship between the corpus callosum and motor memories? Do motor memories process in one hemisphere and are then shared with the other- if so, how? Thank you so much for your time and patience!

One Answer

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.
