Network parameters and mean-field results from scanning through different working points. Working point (μ, σ) combines mean input μ and noise intensity of input σ. (A) External excitatory ν_ext,E and inhibitory ν_ext,I Poisson rates required to set (μ, σ) and resulting firing rates ν. (B) Transfer function N_cn,s of spiking model and fitted rate-model approximation with low-pass filter for selected (μ, σ) (top: amplitude, bottom: phase). (C) Fit results (time constants τ and excitatory weights w_E) and fit errors η. The inhibitory weights are w_I = −gw_E with g = 5. Star marker in panels (A) and (C) denotes target working point (10, 10) mV. Similar displays as in Senk et al. (2020, Figure 5).
