Functional centrality and anatomical CR are inversely related. (A) Ranked betweenness centrality of the considered nodes. pCC and SMA, after mCing (FPN), are the two most central hubs. In the next analyses, to address the statistical significance of the results, we reported in the plots the correlation values and their P values, the obtained bootstrap confidence intervals and the results from the permutation tests. (B) BC and anatomical CR for the first 10 most central nodes are strongly anticorrelated (r = −0.83) with hierarchical clustering (left) and (r = −0.67) with the multiscale community detection (right)). (C) The same analysis extended on the whole sample of nodes still shows an inverse relationship, although with a lower strength (r = −0.37) with hierarchical clustering (left) and (r = −0.31) with multiscale detection (right)). (D) No significant linear relationship between BC and the functional CR was obtained, see the bootstrap confidence intervals with hierarchical clustering (left) and with multiscale detection (right)). On the whole sample, BC and functional CR are not linearly related.
