Included regions exceeded an extent threshold of five continguous voxels and p < 0.05 (FWE-corrected). For each region, the voxel with the maximum T value is described. The voxel coordinates refer to the MNI template. The laterality (L/R) of the clusters is described [left (L), right (R), medial (M)] and corresponding anatomical labels (Region), BAs, and cluster sizes (k) are listed.
