The human cortical connectome requires a lower coupling gain to display ignition than surrogate models.

(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

DPR_hw

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

SW_hw

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.
