Resting-State Temporal Synchronization Networks Emerge from Connectivity Topology and Heterogeneity

Dynamical range of the anatomically-constrained phase oscillators’ network.
a) Time evolution of the phase difference between two nodes of the anatomically-connected heterogeneous Kuramoto model, for three values of the global coupling G. Left: in the weakly connected case (G = 0.025) the phases run almost independently; middle: with moderate coupling (G = 0.25) the phases tend to lock for short periods of time, as revealed by the deflections in the trajectory of the relative phase, indicating the presence of metastability; right: with strong coupling (G = 1.25) the phases are locked. b) Corresponding oscillations of the two nodes, for the three dynamical regimes.
