Excitability heterogeneity, in combination with inter-node synaptic coupling, collectively achieves Lyapunov stability against external stimulation at the macro-scale.

<p>Sub-figure (a) shows how the stability of a homogeneous and heterogeneous network changes with . The heterogeneous network maintains stability irrespective of the coupling between the two regions. The results are for mV. Sub-figure (b) shows that a homogeneous network becomes unstable even...
