Representative SL and NI distributions of (A) regular, (B) small-world, and (C) random undirected networks with heterogeneous excitabilities. The green squares correspond to NI⁽ⁱ⁾, whilst the brown triangles are SL⁽ⁱ⁾ values. The nodes were sorted by their excitability $I_0^{(i)}$. (D) displays the weighted Kendall's rank τ (blue diamonds) and Pearson correlation ρ (red pentagrams) across different undirected networks with heterogeneous excitabilities (Rg: regular networks; SW: small-world networks with p = 0.1; and R: random networks). Node excitabilities $I_0^{(i)}$ were set to −1.2 apart from a group of six randomly chosen hyper-excitable nodes with $I_0^{(h)}=-0.1$. Error bars in (D) account for the variability of τ and ρ across 10 network realizations and 5 random selections of hyper-excitable nodes per each network. Other parameters are the same as in Figure 1.
