Critical behaviour of the stochastic Wilson-Cowan model
Fig 3
Firing rate for neuron at the critical point and far from it.
Firing rate measured in numerical simulations as a function of time for wE + wI = 13.8, h = 10−5. Upper row: w0 = 1 (E dominates) (A), middle row: w0 = 0.2 (E dominates) (C), lower row: w0 = 0.1 (E/I balance) (E), left column: N = 103, right column: N = 105 (B,D,F). Blue lines represent the firing rate of the network, while gray dots represent single neuron spikes. Red lines show the value of the firing rate R0 at the fixed point of the dynamics. Note that this value can be quite different from the mean firing rate (green lines), when large non linear effects are present.
