WebJun 1, 2024 · The celebrated Fitzhugh–Nagumo (FHN) model [38] is a model of choice for the study of nerve impulse propagation in cardiac and nerve tissue. It is highly tractable, unlike the Hodgkin-Huxley model [39], and as a result, has been the object of multiple studies. Its dynamics has been extensively discussed in Ref. [40]. http://www.scholarpedia.org/article/FitzHugh-Nagumo_model
