The current paper investigated the generalized FitzHugh–Nagumo model. We have shown that symmetric bursting behaviors of different types could be observed in this model with an appropriate recovery term. A modified version of this system is used to construct burst-ing activities. Furthermore, we have shown some numerical examples of delayed Hopf bifurcation and canard phenom-enon in the symmetric bursting of super-Hopf/homoclinic type near its super-Hopf and homoclinic bifurcations, respec-tively.
