^aPeak MNI Coordinates.
^bWe first identified clusters of contiguously significant voxels at an uncorrected threshold p < 0.001, as also used for display purposes in the figures. We then tested these clusters for cluster-level FWE correction p < .05 and clusters with at least 30 voxels were survived. Voxel size = 3*3*3.
^cThe brain regions were referenced to the software Xjview (http://www.alivelearn.net/xjview8) and double checked with atlas.
