Experimental setup. A 7-digit sequence of numbers, which was a combination of 1, 2, 3, or 4 in a random order, was displayed on the monitor for 2500 ms. Participants were instructed to repeatedly push the 1, 2, 3, or 4 numbered buttons as accurately and quickly as possible with their right fingers. Each button was labeled with a number representing the finger: 1, 2, 3, and 4 represented the index, the middle, the ring, and the little finger, respectively. This task was repeated before and after high frequency rTMS on randomly assigned M1 or SMA. A week later, the same task was repeated again before and after rTMS on the other area at this time (cross- over study design).
