Grand ERP-image plots over the electrode Cz for SHAM (upper row), rhTMS (middle row), and their difference - rhTMS-SHAM (lower row) conditions in the IAF-1 (first column), IAF (second column), and IAF+1 (third column) groups. In each plot, participants are sorted by the change rate of the amplitude between the rhTMS and SHAM, and single-subject P3 peak is marked with a dot. Vertical lines at 0 ms indicate stimulus onset. In the lower part of each plot, the grand average ERPs are presented in the P300 time window (100-500 ms).
