For hemisphere, L = left, R = right; BA = Brodmann Area; x, y, z: Montreal Neurological Institute (MNI) coordinates listed only for clusters with volume greater than 15 voxels. All coordinates listed correspond to global maxima within a region (voxels and t-value given) or local maxima within a region (t-value not given).
