Figure 13. Excitatory-inhibitory feedback loop for synchronous gamma oscillations with irregularly firing neurons.
Computer simulation of a model with two neural populations (pyramidal cells and interneurons) in a sparsely connected random network. The network shows a collective oscillation at 55 Hz (see population rates, and the power spectrum), whereas single neurons fire spikes intermittently in time at low rates (2 Hz for pyramidal cells, 10 Hz for interneurons; see rastergrams).
