Fig. 8: Influence of global model parameters in frequency-specific envelope functional connectivity patterns.

For 4 simulations obtained with different Global Coupling strength (K) and Conduction Delays 〈τ〉, we report the frequency-specific functional connectivity (FC) estimated as the correlation matrices of the envelopes of signals band-pass filtered in the delta (δ), theta (θ), alpha (α) and beta (β) frequency bands. The colormap limits of the matrices are scaled by the maximum absolute correlation and centred at zero. Next to each matrix, each of the N = 90 brain areas is represented as a sphere placed in its centre of gravity and colored according to the maximum envelope FC to any other brain area (same colorbar applied to all spheres, scaled between −1 and 1).
