From: Distinct and competing interneuron populations can generate fast and slow gamma in oscillatory models of CA1

Figure 1

A. Connectivity scheme for firing-rate two-gamma model. CA3 and EC denote inputs, E denotes excitatory population, and IF and IS denote the interneuron populations with brief and long post-synaptic effects, respectively. B. Graph shows the oscillation frequency of the noise-free network across a range of input balance to IS and IF. Blue region indicates bistable regime with co-existing fast and slow oscillatory states. Such a bistable regime only exists with high IS - IF connectivity. C. Time courses of each population's synaptic variable show spontaneous switching between fast and slow gamma states due to additive noise in inputs to IS and IF.
