The 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 the following year, describes a prototype of an excitable system (e.g., a neuron). The FHN Model is an example of a relaxation oscillator because, if the … See more • Autowave • Biological neuron model • Computational neuroscience • Hodgkin–Huxley model See more • FitzHugh R.

WebConsidering the improved FitzHugh-Nagumo (FHN) neuron system stimulated by external electric field in Ref. [12], the governing equation of model was constructed and can be expressed as (1) {ε dx dt = x − x 3 3 − y + I ext dy dt = ax + by + d + rE dE dt = ky + E ext where x, y, E stand for the membrane potential, slow current and electric ... WebApr 6, 2024 · In this paper, stochastic FitzHugh–Nagumo lattice system with nonlinear noise in weighted spaces is considered. Firstly, the well-posedness of solution of such system in a weighted space \(L^2(\Omega ,l^2_\sigma \times l^2_\sigma )\) is established, based on which we further prove the existence and uniqueness of weak pullback mean … WebJul 25, 2024 · This situation models the appearance of abnormal electrical activity in the heart, where the disturbance is a cardiac tissue in damage. We present a Finite Element Method (FEM) scheme for the two-dimensional FitzHugh-Nagumo (FHN) system to simulate the spiral-generation mechanism in cardiac tissue. This scheme is based on the … graham coffey and co solicitors
