Figure 4:

Robustness. Network dynamics are nearly identical for different sizes. Several examples shown over a range of different network sizes (N=400–2000), and levels of sparseness (0.125–0.62). Different combinations are color coded as shown in legend. (b) Network is robust to randomness in weight matrix. Three runs are shown for a weight matrix in which all non-zero synaptic efficacies have the same value (solid lines) and three runs in which the non-zero weights were chosen from a uniform random distribution (dashed lines). The results are quite similar
