From: Investigating the Correlation–Firing Rate Relationship in Heterogeneous Recurrent Networks
The strength of background noise modulates the correlation–firing rate relationship. (A) Each panel shows firing rate vs. susceptibility (Ŝ), computed for a family of networks generated by modulating the strength of excitation (\(W_{EE}\) and \(W_{IE}\)) with various background noise levels (see Eq. (17) for \(\sigma_{E}\) and \(\sigma_{I}\) definitions). (B) Population-averaged effective parameters \(\langle g_{I} \rangle\) and \(\mathcal{E}_{\mathrm{rev}}\), for each network displayed in (A); see Eq. (28) for \(\mathcal{E}_{\mathrm{rev}}\)
