HCA of BrainMap-based ICNs at d = 20 and d = 70 provide insight into how low-model order networks fractionate into high-model order sub-networks. (A) Network clustering of the d = 20 decomposition revealed three clear groupings of highly similar networks: emotional and interoceptive networks (blue), motor and visuospatial networks (green), and visual networks (cyan). The remaining components were associated with higher cognitive processes (warm colors). The cognitive networks were behaviorally dissimilar across components and other network groups, as indicated by high branching points in its dendrogram. (B) Network clustering of the d = 70 decomposition exhibited generally similar network organizational properties with the d = 20 dendrogram, but included subtle fractionation properties indicative of non-homogenous behavioral functions. The left–to–right ordering of networks in the above dendrograms are the same as presented in Figure 5. Vis, visual; M/V, motor and visuospatial; Cog, cognitive; Emot/Int, emotional and interoceptive.
