"We found that adaptive learning with the hand affects cerebellar–motor cortex connectivity, not only for the trained hand, but also for an untrained leg muscle, an effect likely related to intereffector transfer of learning."
"The measurements from these subjects showed that the connectivity between the cerebellum and the motor cortex changed not just for the areas of the motor cortex that controlled the right hand, but also in the areas known to control the right foot."
