Figure 1. Modulation of corticospinal excitability (CSE, panel A) and short-interval intracortical inhibition (SICI, panel B) across the three conditions in the SICI session. Statistically significant differences in the interaction term are described in the main text. CSE is measured as unconditioned motor evoked potential (MEP) amplitude. Inhibition was calculated as follows: [1 – (MEPCS + TS / MEPTS)] * 100. Error bars represent standard error of mean. ***p<0.001, **p<0.01, *p<0.05, ^p<0.1.
