Perception of intensity and pleasantness after S1 rTMS. A, Subjects rated the intensity and pleasantness of fast and slow brushing on the palm and back of the hand before and after 20 min of 1 Hz rTMS. The subjects who showed a drop in 2PD performance after rTMS to S1 (n = 14) also showed an increase in intensity ratings but not in pleasantness ratings (averaged across brushing types) after rTMS to S1. Five subjects who did not show a drop in 2PD accuracy are not included in graph. *Single-sample t test, p < 0.05. Error bars indicate ± SEM. Intensity: S1 before, M = 41.9, SD = 26.0; S1 after, M = 46.1, SD = 27.5; vertex before, M = 45.6, SD = 23.2; vertex after, M = 43.4, SD = 24.7; pleasantness: S1 before, M = 64.6, SD = 14.7; S1 after, M = 65.9, SD = 15.9; vertex before, M = 64.5, SD = 15.2; vertex after, M = 64.3, SD = 15.3. B, Changes in 2PD accuracy from before to after rTMS significantly predicted changes in ratings of brushing intensity.
