Methods. A, Setup for the behavioral task used in all three experiments. Participants viewed the vertical computer monitor for visual feedback about the task and trained with the right hand before switching to the right foot to assess hand-to-foot transfer. For foot movements, the tablet was placed vertically and the foot was propped up. B, Coil placement to measure CBI. This technique requires paired-pulse stimulation in which one TMS coil is placed over M1 (test) and the other over the cerebellum (condition). To determine CBI for the right hand muscle (FDI), the conditioning pulse was delivered over the right cerebellum 5 ms before the test pulse was applied over the left M1 representation of FDI. The same procedure was followed to determine CBI for the right leg muscle (TA), with the test pulse applied over the left M1 representation of TA.
