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!

    $\begingroup$ Almost all parts of the brain have a relationship, but what deems a neuronal relationship significant? Maybe this will help (pay-wall): onlinelibrary-wiley-com.ezproxy2.acu.edu.au/doi/abs/10.1002/… $\endgroup$

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.
