Regions in boldface formed the set of anterior regions [Montreal Neurological Institute (MNI) coordinate Y > 16 for the centroid of these regions + IFGoperc], and the regions in italics formed the set of posterior regions (MNI Y < −40 for the centroid of these regions + SMG). These posterior and anterior regions were used in the computation of the PAx, which establishes whether there is a consistent posterior–anterior pattern, or vice versa (see Eq. 4).
