Note: L = left hemisphere. R = right hemisphere. BA = Brodmann Area. Vol = volume in microliters. Talairach coordinates reflect center of mass. All clusters listed were significant at F(1,28) > 4.2 for P<0.05 (0.025 two-tailed) voxelwise corrected for multiple comparisons. Cohen’s d reflects effect size between groups.
