↵ a TMS site as index area: coordinates of brain regions to which the TMS site is less sensitive after rTMS.
↵ b-d Three movement-related activations as index areas. Coordinates of brain regions showing increased coupling with left sensorimotor region (b), left dorsal premotor region (c), and left SMA after real-rTMS (d), compared with sham-rTMS.
↵ e p < 0.05 (small volume correction, using values in Table 2).
