Note. Location, volumes, and coordinates from Talairach and Tournoux (1988) for the center of mass for areas of activation. Significance criteria: ANOVA F[20] > 6.06, p < 0.05 (corrected); t[20] p < 0.05 (corrected). Significance criteria for two-tailed correlations:
* indicates p < 0.05 (corrected).
