Figure 2.

Characteristic Length $r_0$ of the neuronal network model. The zero crossings of the CCF shown in Fig. 1 are plotted in linear–linear (left), log–linear (middle) and log–log (right) axis. Top three panels correspond to different system size L and bottom three panels to different box length W. Different symbols correspond to the values of the control parameter $\sigma$ denoted in the legends. Dashed lines are visual aids to emphasize the predicted logarithmic behavior for both sub-critical and super-critical regimes (open circles) and the linear dependence expected for the critical regime (filled circles). Open triangles are used to denote results obtained for intermediate values of $\sigma$. In all cases, error bars are omitted, since error estimates are smaller than symbol size.
