  • All clusters were maintained from a p< 0.01 threshold (corrected for whole brain) except for t values emphasized by bold letters (p > 0.01) and underlined (uncorrected cluster). BA, Brodmann's area; x, y,z, Talairach and Tournoux (1988) peak voxel coordinates in millimeters; t, peak voxel t value.
