RS = right stimulation; LS = left stimulation; Voxels = the number of voxels in the cluster; MAX = the value of the maximum z-statistic within the cluster; MAX X/Y/Z (vox/mm) = the location of the maximum intensity voxel, given as X/Y/Z coordinate values in standard space coordinates (mm); COG X/Y/Z (vox/mm) = the location of the centre of gravity for the cluster (a weighted average of the coordinates by the intensities within the cluster); PRG = precentral gyrus; POG = postcentral gyrus; PO = parietal operculum cortex; H = Heschls gyrus (includes H1 and H2); INS = insular cortex; CO = central opercular cortex; CER = cerebellum; L = left; R = right.
