Table 3.

After averaging within each of the original 82 anatomical labels using data generated from the 620‐parcellation scheme, for both μ and nodal efficiency, the ratio of nodal efficiency to μ or “embeddedness” was computed and the regions were sorted and listed from high to low with respect to this ratio

Regions ranked higher thus not only (1) have high nodal efficiency, but also (2) have slower efficiency decay. Regions with the highest degrees of embeddedness are primarily the bilateral subcortical structures including the thalamus and basal ganglia (pallidum, caudate, and putamen), the regions forming the limbic system (insula, nucleus accumbens, and subdivisions of cingulum), the precuneus and neighboring parietal regions, and the medial orbitofrontal cortex.
