FitzHugh–Nagumo

Waves produced by an excitable FitzHugh–Nagumo PDE. Introduction We will here take a closer look at waves produced by an excitable FitzHugh–Nagumo PDE in a periodic 1D domain, in a periodic 2D domain.

ODEs for the FitzHugh–Nagumo well-mixed system Introduction The FitzHugh–Nagumo (FN) model is commonly used as a toy model for neuronal excitation. Description Everything is well-mixed and two ODEs are solved for two variables, $u$ (voltage) and $v$ (recovery variable).
