Simulated metastability and synchrony as a function of coupling strength. (A) Metastability (black line) and (B) synchrony (black line) generated using the Kuramoto oscillator model as a function of structural coupling strength k and comparison with empirical metastability and synchrony for each resting-state network (RSN). Color-coded dashed lines and shaded bands indicate, respectively, the mean and standard deviation of the empirical data across all participants. (C) Color-coded phase circle diagram at t = 390 s for coupling strengths at which the simulated metastability is maximized. Solid lines in black represent the amplitude of the order parameter, R(390 s) = 0.3, 0.3, 0.1, 0.4, 0.4, and 0.6, respectively corresponding to k = 5, 6, 5, 5, 8, and 6. The color of each oscillator represents the natural frequency deviation from the mean (in the color bar, S is the standard deviation of the natural frequencies). DMN = default mode network, CEN = central executive network, SAL = salience network, SMN = sensorimotor network, VN = visual network, AN = auditory network.
