A theory for self-sustained balanced states in absence of strong external currents

Fig 7

Correlations in the balanced regime.

(A) Population averaged Pearson correlation coefficients among the partial input currents versus N. (B) Population averaged Pearson coefficients of the total input currents. Inset: Correlation coefficients R^E and R^I of the excitatory and inhibitory firing rates versus the system size N. The red dashed line refer to a power law decay 1/N. The data are averaged over 10 different realizations of the random network, and over a time interval t = 300, after discarding a transient of duration 500. For this figure I₀ = 0 and J₀ = 1.5.
