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

Fig 6

Rate chaos approaching the thermodynamic limit.

(A) Average firing rates and synaptic efficacy [w] as a function of network size N. Symbols refer to direct network simulations, while solid lines represent DMF predictions. (B) Variances of the total inputs for increasing N predicted by DMF theory. (C) Autocorrelation function of the excitatory synaptic input for different N. Inset: Decorrelation times versus N. (D) |A_E|,|A^I| versus N. The magenta dashed line indicates a power law decay N^−1/2. For this figure all simulations were performed by averaging a time interval , with I₀ = 0 and J₀ = 1.5.
