Effect of rTMS on 2PD accuracy. Participants were tested on 2PD before and after 20 min of inhibitory 1 Hz rTMS on 2 separate days. During the active session, rTMS was directed to S1 and, during the control session, rTMS was directed to the vertex. The 2PD task was administered as 2 descending series of blocks at tip distances of 2–10 mm (see Materials and Methods for details). Each block contained 5 trials of 2-point stimulation and 5 trials of 1-point stimulation. 2PD accuracy was reduced significantly more after rTMS to S1 than after rTMS to the vertex. In addition, there was a marginally significant interaction between rTMS session and distance. Post hoc tests showed that 2PD accuracy was significantly reduced after rTMS to S1 at the smallest distance tested. S1 before, M = 58.1, SD = 11.1; S1 after, M = 50.8, SD = 9.7; vertex before, M = 56.3, SD = 9.4; vertex after, M = 58.6, SD = 9.2. *One-tailed p < 0.05. Error bars indicate ± SEM.
