(A) One example of the unweighted surrogate connectomes (uSCs) matrices, in which connections were normalized to make reliable comparisons with

Human

(each purple entry was set to 1.332x10-2). The

DPRhw

networks disrupt the connectivity pattern but preserve the degree distribution. The

SWhw

networks display a small-worldness value close to the

Human

. (B) One example of the weighted surrogate connectomes (wSCs) matrices. The colour bar shows the connection weights in a log-scale. (C-D) Bistable range of the Human compared to either uSCs (C) or wSCs (D), highlighting the bifurcation G- (left) and G+ (right) points. The orange dashes (blue dashes) show the range of values for G- (G+) in surrogate connectomes.
