aAll coordinates are from the group analysis (p < 0.05 FDR-corrected, spatial extent threshold of 5 voxels) given in MNI space, as well as the Z score and the cluster extent size (see also Fig. 5). Coordinates without extent values are subclusters belonging to the next closest cluster.
*Significant after clusterwise FWE correction (p < 0.05). ζ belongs to cluster 54, −6, −3.
