Fig. 6: Characterization of metastable oscillatory modes (MOMs) emerging from the system.

For different Global Coupling strength (K) and Conduction Delays 〈τ〉, MOMs are characterized in terms of duration (i.e., consecutive time that the power remains above threshold), size (i.e., the number of units simultaneous displaying power above threshold) and occupancy (i.e., the proportion of time that the power is detected above threshold over the entire simulation), for each frequency band. This demonstrates that the same network structure, i.e., the connectome, can exhibit different oscillatory modes organized in space and in time, depending on global parameters of the system. In the critical range of parameters (Optimal Range), oscillations in the alpha frequency band emerge more frequently and involve more units. Globally synchronized delta oscillations—as typically observed in states of reduced consciousness—are associated to an increase in the global coupling strength (Strong Coupling). Error bars represent 1 standard deviation. See also Supplementary Movie 1.
