Note: Region names are based on the Freesurfer parcellation (Destrieux et al., 2010). x, y, z = MNI coordinates for the peak node within each cluster; t-values = t-value for the peak node. LH = Left hemisphere; RH = Right hemisphere. Clusters are thresholded at alpha <0.05 (corrected; voxel threshold of p <  .005 and cluster size >88 mm²). *Cluster also survives a more stringent threshold (voxel threshold of p <  .001 and cluster size >55 mm²).
