Results were thresholded at voxelwise p<.001 and corrected for multiple comparisons by permutation analysis. Cluster size was thresholded at p<.05; only clusters greater than 495 mm³ were considered significant. MNI coordinates for the clusters are the center of the mass, whereas MNI coordinates for the regions are the local maxima.
