Fig. 1: Network of neural masses – test 1.
From: Patterns of synchronized clusters in adaptive networks
The network is split into two clusters a by stimulating N1 nodes with a current pulse with normalized height 0.2 and 100 ms duration, and not stimulating the remaining N2 nodes. Depending on the values of N1 and the synaptic coupling strength σ, the stimulated cluster can produce stable brain oscillations (b) (blue region) or present persistent activity corresponding to a constant population firing (b, green and dark blue regions). The dashed black lines mark the edges between the three regions and have been computed semi-analytically (see Supplementary Note 5). c–e Time evolution of the state variables E1 (solid blue) and E2 (dashed red) for the set of parameters corresponding to dots in panel (b). f Frequency of the collective oscillations at the three values of σ marked by colored vertical bars in (b). Each curve in (f) has the same coloring as the corresponding bar. By varying N1, the network can produce oscillations in the β − γ range.
