IPC: Inferior parietal cortex, M1: Primary motor cortex, PMC: Premotor cortex, S1: Primary somatosensory cortex, SPL: Superior parietal lobule. A: The kettle condition minus the control condition (uncorrected, P < 0.001) in the patients with RSI > controls comparisons. B: The kettle condition minus the control condition in the controls > patients with RSI comparisons (uncorrected, P < 0.001). C: The ABER condition minus the control condition in the patients with RSI > controls comparisons (uncorrected, P < 0.001). D: The ABER condition minus the control condition in the controls > patients with RSI comparisons (uncorrected, P < 0.001). x, y, z (mm): coordinates in Montreal Neurological Institute (MNI) space. x-coordinate: Plus and minus values indicate the direction of right and left, respectively. y-coordinate: Plus and minus values indicate the anterior and posterior directions, respectively. z-coordinate: Plus and minus values indicate the dorsal and ventral directions, respectively.
