Figure S1: Motor‐evoked potential (MEP) integrated area at baseline (resting; gray), and at the −2500‐ms TMS application time for each reaction time (RT) task (green = simple RT; blue = choice RT; red = go/no‐go RT). Fixed effect means and 95% CI are shown as large markers and error bars, individual subject estimated mean MEP amplitudes are shown as small gray markers, and violin plots represent the distribution of raw data, Means are back‐transformed from the log scale. Note that MEP amplitude was significantly (*) larger for all three RT tasks at the −2500‐ms TMS application time compared to baseline.

Figure S2: Motor‐evoked potential (MEP) integrated area as a function of TMS stimulation time for each reaction time (RT) task (green = simple RT; blue = choice RT; red = go/no‐go RT), showing fixed effect means and 95% CI for each task. Note that means are back‐transformed from the log scale. Asterisk (*) indicates significant difference between tasks at each time point. Dagger (†) indicates significant difference between time points (gray = all tasks, red = go/no‐go only).
