Model connectivity.

Abstract

Left: One population as described in Eq (1). u is the fast excitatory AMPA synaptic activity, v the inhibitory GABA activity, and n the slow excitatory NMDA activity. Feedforward excitation to the AMPA synapses (u) triggers activity in the system. Middle: An example network with N = 7 populations. The elements are coupled in an all-to-all fashion as shown on the right. Right: Connectivity between two populations, each with three components as shown in the left panel. The populations are connected with excitatory (ce) and inhibitory (cei) coupling as described in Eq (2).</p
