摘要: 讨论了 F itzHugh Nagumo的系统特性, 用 Matlab 的编程功能仿真 F itzHugh Nagumo系统在噪声 激励下的几种性态: 系统可以在噪声激励下由极限环变为焦点; 足够大的噪声可以使系统的 Lyapunov 指数收敛。因此, M atlab可以描述 F itzHugh Nagumo系统的非常有规律的动力学行为, 提高了学生的实 践编程能力,...
It helps in learning how to compute a second derivative in the MATLAB® software and use a modification of the Fitzhugh- Nagumo model. The Fitzhugh-Nagumo model is often used as a generic model for excitable media because it is analytically tractable. It as a simple model to generate ...

In this chapter we will use the techniques of phase plane analysis to analyze a simplified model of action potential generation in neurons known as the Fitzhugh-Nagumo (FN) model. Unlike the Hodgkin-Huxley model, which has four dynamical variables, the FN model has only two, so the full ...

A delay-independent stability and bifurcation conditions for the fractional-order delay-coupled FitzHugh–Nagumo neural model is acquired. By designing a proper P D p controller, we can efficaciously control the stability domain and the time of emergence of the bifurcation phenomenon of the ...
