Talairach space coordinates of the peak location of the source of reduction of beta-band power estimated by the beamformer analysis

Subject	x (mm)	y (mm)	z (mm)	Cortical labels within ±5 mm of the x, y, z coordinates
S1	−38	−29	+58	Left postcentral gyrus; left precentral gyrus; left inferior parietal lobule
S2	−26	−23	+52	Left precentral gyrus; left postcentral gyrus
S3	−32	−17	+58	Left precentral gyrus
S4	−41	−17	+52	Left precentral gyrus; left postcentral gyrus
S5	−54	−23	+43	Left postcentral gyrus; left precentral gyrus; left inferior parietal lobule
Average	−38	−22	+53	Left precentral gyrus; left postcentral gyrus

The cortical labels were obtained using the automated database of Lancaster et al. (2000). They are listed in decreasing order of volume occupied within a 11-mm-side cube centered on the x, y, and z coordinates.
