Representative SL and NI distributions of (A) regular, (B) small-world, (C) random, and (D) scale-free undirected networks with homogeneous excitabilities. The green squares correspond to NI⁽ⁱ⁾, whilst the brown triangles are SL⁽ⁱ⁾ values. The nodes were sorted such that the NI grows monotonously. Parameters: number of nodes N = 64, mean degree c = 4, homogeneous excitability I₀ = −1.2, probability of rewiring to generate the small-world network p = 0.1, and degree distribution exponent of the scale-free network α = 2.6.
