- Connectivity details for networks examined in Sect. 2.2. Here \(W_{YX}\) denotes X→Y connections; e.g. \(W_{IE}\) denotes the strength of excitatory connections onto inhibitory neurons. The parameter \(\sigma_{i}\) denotes the strength of background noise in units of (scaled) voltage, and depends only on cell type (E or I). The parameters \(W_{EE}\), \(W_{IE}\), \(\sigma_{E}\) and \(\sigma_{I}\) will vary in Sects. 2.4 and 2.5; see text for details. For reference, \(W_{XY}=1\) is when the presynaptic input is exactly the average population firing rate (filtered by the synapse) in an all-to-tall homogeneous network.
