Abstract: We consider a model of a circular network of neurons where the functioning of each neuron is described by an equation with two delays. The model under study is a modification considered in the paper of Glyzin et al., where the model of a solitary neuron is based on of the equation with one delay – the Hutchinson equation. We construct discrete traveling waves, i.e., a periodic solution of the system such that all components coincide with the same function shifted by a quantity that is multiple of a certain parameter. To find this solution, we study an auxiliary differential-difference equation of the Volterra type with three delays. For this equation, for any natural $m$ and $n$, we establish the existence of a periodic solution that contains $m$ packets, each of which contains $n$ bursts per period.

Keywords: differential equations with delays, circular system, discrete traveling waves, bursting cycle, periodic solutions, phenomenological model of a neuron.
