The last four columns (coordinates and z-value) refer to the main peak of activation in the cluster. Coordinates refer to Montreal Neurological Institute. Results thresholded at p < 0.05 FDR-corrected. BA = Brodmann areas; k = cluster size; L = left hemisphere, R = right hemisphere. * = significant at p < 0.05 FDR small volume correction.
