Age-related alterations in the modulation of intracortical inhibition during stopping of actions

Figure 3. Modulation of corticospinal excitability (CSE, panel A) and long-interval intracortical inhibition (LICI, panel B) as a function of stop-signal probability (SSP) in the LICI session. CSE is measured as unconditioned motor evoked potential (MEP) amplitude. Inhibition was calculated as follows: [1 – (MEP_{CS + TS} / MEP_TS)] * 100. Untransformed LICI values are presented. Error bars represent standard error of mean. ***p<0.001, **p<0.01, *p<0.05, ^p<0.1.
