The correlation distributions. (A) The functional networks at five sample frequency ranges. The elements of the functional networks are the correlation indices σ_ij defined in the Methods. In each panel, the results of a simulation of the model with a given mean frequency are presented. From left to right the mean frequency is 3, 11, 23, 35, and 51 Hz which lie within the bands θ, α, β, γ, and high-γ, respectively. The frequencies are chosen from a normal distribution with the given mean value and standard deviation 0.1. The axes show the index of nodes which represent ROIs of the structural network. The gray dash lines indicate the boundary of the brain hemispheres. The coupling scale factor is K/N = 0.25 and the noise amplitude is 0.05. The initial phases are chosen from a uniform distribution in the range [−π, π]. The results are averaged over 200 realizations. (B) The distribution of correlations vs. weight (W) and distance (D) of the connections at each frequency. (C,D) The distribution of correlations vs. average natural frequencies of the nodes (ν₀). The colors in panels (C) and (D) show the corresponding connection's weights and distances, respectively.
