Schematic of the local source node network architecture underlying mean field modelling. Excitatory (red circles) and inhibitory (black squares) neurons occupy a volume (left).
Couplings are indicated by black connecting lines. Conceptually both neuron types can be clustered in two subpopulations (middle). Each subpopulation can be then characterized by a mean behaviour under certain conditions (right) and a mean connectivity. (Figure courtesy (Stefanescu Jirsa 2008)).
