WebThe FitzHugh–Nagumo model (FHN), named after Richard FitzHugh (1922–2007) who suggested the system in 1961 and J. Nagumo et al. who created the equivalent circuit … WebOne of the resulting models is the 2-dimensional FitzHugh-Nagumo (FHN) neuron model [FitzHugh, 1961]. The FHN model has been so successful, because it is at the same time mathematically simple and produces a rich dynamical behavior that makes it a model system in many regards, as it reproduces the main dynamical features of the HH model. simplywork biometric touchscreen timeclock https://gatelodgedesign.com
