Model Neurons of Bifurcation Type 2
A neuron is said to be of bifurcation type 2 if the transition that occurs as I crosses I c is a Hopf bifurcation [47, 75, 129]. Examples of model neurons of bifurcation type 2 include the classical Hodgkin-Huxley model, and the Erisir model described in Section 5.3 The Hopf bifurcation in the classical Hodgkin-Huxley model is analyzed in great detail in . For numerical evidence that the transition from rest to firing in the Erisir model involves a subcritical Hopf bifurcation, see , and also Fig. 17.9.
