The peak voxel for each cluster and the corresponding name of the anatomical region are given. Asterisks indicate peak voxels located in the white matter. In these cases, we labeled the brain region in which most voxels in the cluster were located.

BA: Brodmann area. P < 0.05 (AlphaSim correction).
