From: Power spectrum and critical exponents in the 2D stochastic Wilson–Cowan model
(A) Autocorrelation and (B) power spectrum of the single site firing rate in a two-dimensional \(L\times L\) model, in the linear approximation (number of neurons \(N\rightarrow \infty \)), as a function of the distance from the critical point. We set \(L=100\), \({\tilde{w}}_{s,0}=13.8\), \({\tilde{w}}_{0,0}=0.1\), and external input h between \(10^{-4}\) and \(10^{-8}\). The connections between neurons depend on the distance as in Eq. (3), with \(\lambda =1\).
