Figure 11. Effects of changing coupling strength in populations of Hindmarsh-Rose neurons.

Figure 11

Left: Mainly excitatory coupling: an increase in the coupling strength leads to synchronization within and between the neurons in the excitatory (red) and inhibitory (black) subpopulations. Right: Mainly inhibitory coupling: an increase in the coupling strength induces small amplitude oscillations in the inhibitory subpopulation (black) and a chaotic regime in the excitatory neurons (red).
