Figure 5.

Correlation collapse after rescaling for the ferromagnetic 2D Ising and the neuronal model at criticality. Panel (a) 2D Ising model rescaled CCF as a function of W with fixed L (same same data as in Fig. 3e, with $L=600$, $W<L$, $T=2.27$), collapsed as $c_0{C}_W(r)\times W^{\eta }$ v.s. $r/r_0$, with $\eta =0.25$. Panel (b) Collapse for neuronal model, using exponent $\eta =0.54$. For each value of W, points with $r<I$ are shown with a dashed line of the same color. Panels (c,d) relative collapse error as a function of critical exponent $\eta$ for the Ising and the neuronal model, respectively. All simulation parameters are as in previous figures.
