All significant activations at P < 0.001 (uncorrected, k > 5 voxels) are listed. PMv, ventral premotor cortex; LOC, lateral occipitotemporal cortex; SI, primary somatosensory cortex, SMA = supplementary motor area.

^aFWE-corrected peak P values based on small volume correction using coordinates from Petkova et al. (2011).

^b,cFWE-corrected peak P values based on small volume correction within SI as defined by the significant activations obtained from the tactile localizer run for the left arm^b or right arm^c (see Supplementary material for details).
