The left panels plot the mean TMS-induced resting peak-to-peak MEP amplitudes stratified by trial number within the block for the three parameter condition sets tested. The right panels compare early to late trials across conditions. In the blocked Duty Cycle experiment, no significant differences between early and late trials were found in the sham, 10%, 30%, or 50% conditions (p=0.31, 0.31, 0.81,0.81, paired t-tests). Similarly, in the blocked PRF experiments, no differences were found between early and late trials within the sham, 100, 500, or 1000 Hz conditions when DC was held constant (p=0.09, 1.0, 1.0, 1.0, paired t-tests) or adjusted (p=0.92, 1.0, 1.0, 1.0, paired t-tests). Error bars represent standard error, and p-values are adjusted with the Holm-Bonferroni method (α = 0.05).
