Figure 4. Experimental procedure. At the start of the session, participants first practiced the task. Immediately after familiarization, behavioral reactive and proactive inhibition was assessed (behavioral assessment). Next, TMS was prepared and delivered during the task. In total, there were 10 TMS task blocks and 1 TMS rest block, which were presented in the same order across participants. There were two different types of task blocks: one with certain-go trials (i.e. stop-signal probability [SSP] = 0%) and one with uncertain-go trials (i.e. SSP = 20 and 40%). During the rest block, resting measures of corticospinal excitability and intracortical inhibition were assessed.
