A theory for self-sustained balanced states in absence of strong external currents
Fig 10
Fixed point regime in the spiking network.
(A) Raster plot of a subset of excitatory (orange) and inhibitory (blue) neurons showing tonic firing patterns. (B) Sample synaptic input to two neurons in the excitatory and inhibitory populations (solid line) compared with the mean-field rate model prediction (dashed line). (C) Maximum real eigenvalue of the heterogeneous perturbation Jacobian (symbols) and the random matrix theory prediction (solid lines) for varying values of external input I0. (D) Critical coupling strength Jc estimated from the generalization of the Girko’s law as a function of network size N. For this figure J0 = 0.1, I0 = 1.2,
