Description
The FitzHugh-Nagumo model
is a two-dimensional simplification of the Hodgkin-Huxley model of spike generation in squid giant axons. Here,
- V is the membrane potential,
- W is a recovery variable,
- I is the magnitude of stimulus current.
This system was suggested by FitzHugh (1961), who called it "Bonhoeffer-van der Pol model", and the equivalent circuit by Nagumo et al. (1962).
