WebNov 9, 2024 · A question about FitzHugh-Nagumo model. I`ve been trying to built the FitzHugh-Nagumo model with a changeable input,but I failed to make the input changeable and I was unable to figure out why. I defined three variables which I thought they should be the same,but only the variable 'eq1' and the way I put in the comment worked out,the … http://people.ku.edu/~erikvv/latticefhn.pdf

Webmodel. One year later, Nagumo et al. provided an analog electrical circuit in [47]. The model is now widely known as the FitzHugh-Nagumo model. With these ideas in mind, a simple model which can provide excitable and oscillatory properties is the diffusion-less underlying ODE system of (1) with a constant c. Indeed, it is well known that if jcj< 1, WebThe Fitzhugh-Nagumo model is often used as a generic model for excitable media because it is analytically tractable. You will use it as a simple model to generate traveling …
