Fitzhugh-nagumo
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 waves by the addition of a diffusion term: a second derivative in spatial coordinates. In this chapter, you will modify the Fitzhugh-Nagumo model introduced in Chapter 15 in ...

WebLow-cost accurate digital realization of the spiking neural networks is crucial to investigate the behaviors of human brain performance. This paper presents a multiplierless burst-mode Fitz-Hugh Nagu WebSecondary Bifurcation of the Turing Pattern. This is a simplified version of the HH model which shows spiking activity. FitzHugh (1961) observed that the gating variables n and h involve slow kinetics relative to the variable m. To electronically simulate an animal nerve axon, Nagumo et al. [Ill] made an active pulse transmission line using ...
