To test the robustness of chimera patterns with respect to changes in the structure of the network, we study the following …
WebOct 7, 2016 · In 1961, R. Fitzhugh and J. Nagumo proposed a model for emulating the current signal observed in a living organism’s excitable cells.This became known as the FitzHugh-Nagumo (FN) model of …
WebFurthermore, the correctness and effectiveness of the proposed FitzHugh-Nagumo neuron model with state-dependent impulsive effects are verified by circuit simulation. Finally, the conclusions of this paper are analyzed and summarized, and the effects of random factors on the electrophysiological activities of neuron are discussed by numerical ... 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 ...
