Group-level statistical parametric map showing the categorical comparison of hemodynamic changes in the motor imagery task (whole-brain uncorrected <i>P</i> < 0.001).

<p><b>Upper left</b>: Comparison of patients with RSI > controls in the kettle condition relative to the control condition. <b>Upper right</b>: Comparison of controls > patients with RSI in the kettle condition relative to the control condition. <b>Lower left</b>: Comparison of patients with RSI > controls in the ABER condition relative to the control condition. <b>Lower right</b>: Comparison of controls > patients with RSI in the ABER condition relative to the control condition. z (mm): z-coordinate in Montreal Neurological Institute (MNI) space, which is the basic brain template from the MNI. Plus and minus values indicate the dorsal and ventral directions, respectively. Red bar indicates a T value. M1: primary motor cortex, S1: primary somatosensory cortex, SPL: superior parietal lobule.
