Fig. 1From: Mathematical Frameworks for Oscillatory Network Dynamics in NeuroscienceBifurcation diagram of the Hodgkin–Huxley model as a function of the external drive I. The green lines show the amplitude of a stable limit cycle and the blue lines indicate unstable limit-cycle behaviour, both born from Hopf bifurcations. The solid red line shows the stable fixed point and the black line shows the unstable fixed point. Details of the model are provided in the Appendix Back to article page
