Coordinates of the regions of interest used for the primary motor and primary somatosensory representation of the hands and feet.

	MNI coordinates
ROI	Right hemisphere			Left hemisphere
	x	y	z	x	y	z
HANDM1	41	−20	62	−41	−20	62
HANDS1	42	−35	65	−42	−35	65
FOOTM1	9	−26	76	−9	−26	76
FOOTS1	9	−42	74	−9	−42	74

Note. Coordinates represent locations of peak voxels (cf. [26]) as centers for the construction of spherical masks with radius 8 mm. Due to overlapping spheres in the primary motor and primary somatosensory feet areas, the coordinates of the x-axis were slightly modified from originally 6 to 9 (right) and −6 to −9 (left) in M1 and 10 to 9 (right) and −10 to −9 (left) in S1, respectively. M1, primary motor cortex; S1, primary somatosensory cortex; MNI, Montreal Neurological Institute space; ROI, region of interest.
