Stereotaxic Talairach coordinates of peak activation obtained with p < .005 (uncorrected). Coordinates of peak
activation are reported for regions having atleast 5 significant voxels. * indicates that the peak was identified using a
ROI mask as clusters of activations spanned across several brain regions.
