Model diagram and time series of a bursting solution. (a) Model diagram showing excitatory (red connections) and inhibitory (blue connections) interactions between subpopulations of pyramidal neurons (PYR and PYR’) and inhibitory interneurons (PV+ and SOM+). The post-synaptic potential of a subpopulation, which is the output of \(h(t)\), is multiplied by a synaptic coefficient \(C_{i}\) before being received by another subpopulation. (b) Time series of a bursting solution for the parameter set in Table 1. The panels from the top to the bottom show the time courses of post-synaptic potentials of PV+ (\(v_{3}\)), PYR (\(v_{0}\)), SOM+ (\(v_{2}\)) and the local field potential (LFP), i.e. \(A \tau _{a} p + C_{2} \tau _{a} v_{1}- C_{4} \tau _{b} v_{2} - C_{7} \tau _{g} v_{3}\)
