Figure 4a, b illustrates the significant interaction effects for corticospinal excitability in the left and right M1, respectively. Figure 5 denotes a significant interaction effect for SICI in the right M1
CSE corticospinal excitability (% maximal compound action potential), SICI short-interval intracortical inhibition (% test pulse size), ICF intracortical facilitation (% test pulse size)
