چکیده:

In this paper, a four-neuron ring with self-feedback and delays is considered. The main purpose of this paper is to extend the local periodic solutions globally after certain critical values of delay by using the global Hopf bifurcation theorem for delay differential equations and the Bendixson’s criterion for high-dimensional ODE
