Exploring the Fitzhugh-Nagumo Model

Pascal Wallisch

In this chapter we will use the techniques of phase plane analysis to analyze a simplified model of action potential generation in neurons known as the Fitzhugh-Nagumo (FN) model. Unlike the Hodgkin-Huxley model, which has four dynamical variables, the FN model has only two, so the full dynamics of the FN model can be explored using phase plane methods.
