Clusters achieving p< 0.001, uncorrected, are reported.

For each cluster, the peak location is given in MNI coordinates, accompanied by location in terms of Brodmann’s area and sulcal/gyral locus. T values represent the peak voxel activation within each cluster. Clusters have been thresholded at 17 voxels (136 mm³), as Monte-Carlo simulation of 1000 iteration (AlphaSim, AFNI package). suggests whole-brain p<.05 at cluster size treshold of k=17, with the individual voxel detection probability threshold of .005.
