Synchrony and canards in two coupled FitzHugh--Nagumo equations
Bruno F. F. Gonçalves, Isabel S. Labouriau, Alexandre A. P. Rodrigues
We describe the fast-slow dynamics of two FitzHugh--Nagumo equations coupled symmetrically through the slow equations. We use symmetry arguments to find a non-empty open set of par…

Bifurcations and canards in the FitzHugh-Nagumo system: a tutorial in fast-slow dynamics
Bruno F. F. Gonçalves, Isabel S. Labouriau, Alexandre A. P. Rodrigues
In this article, we study the FitzHugh-Nagumo --fast-slow system where the vector fields associated to the slow/fast equations come from the reduction of the Hodgin-Huxley m…
