Coordinates depict voxel with the highest t-value.

Max t: maximum t-score; No. Voxels: number of voxels; PrCG:precentralgyrus;

PoGG:postcentralgyrus; ACC: anterior cingulate cortex; IPL: intra-parietal lobule;

RO:rolanticopeculum; SMG:supramarginalgyrus; IFG: inferior frontal gyrus;

MI: primary motor cortex; SI: primary somatosensory cortex;

SII: secondary somatosensory cortex.
