An exact firing rate model reveals the differential effects of chemical versus electrical synapses in spiking networks
Bastian Pietras, Federico Devalle, Alex Roxin +2
Chemical and electrical synapses shape the dynamics of neuronal networks. Numerous theoretical studies have investigated how each of these types of synapses contributes to the gene…

Dynamics of a large system of spiking neurons with synaptic delay
Federico Devalle, Ernest Montbrió, Diego Pazó
We analyze a large system of heterogeneous quadratic integrate-and-fire (QIF) neurons with time delayed, all-to-all synaptic coupling. The model is exactly reduced to a system of f…

Firing rate equations require a spike synchrony mechanism to correctly describe fast oscillations in inhibitory networks
Federico Devalle, Alex Roxin, Ernest Montbrió
Recurrently coupled networks of inhibitory neurons robustly generate oscillations in the gamma band. Nonetheless, the corresponding Wilson-Cowan type firing rate equation for such…
