Figure 7

PSD of population activities with different connection probabilityp(same setup as Fig. 6). A microscopic network of \(N=1000\) neurons is simulated with three different connection probabilities: \(p=1.0, 0.2 \text{ and } 0.1\). Synaptic weights w are set such that the rescaled synaptic weights pw is constant. These three microscopic networks share the same mean-field approximation. Notice that the second-order MF is more accurate that the first-order MF even if the connection probability is reduced. Here, the model parameters are slightly modified from Fig. 6 to ensure that population spikes occur in the microscopic simulation 1000 neurons. Parameters are detailed in Appendix E. Superscript (N) of \(A^{N}\) is omitted in the legends
