AnnotationIn this paper, a connected and oriented ring of neurons will be considered. For such a configuration, the dependence of the dynamics of the system on the delay in impulse transmission between neurons and on the number of neurons in the ring is studied. To describe a neuron, the FitzHugh-Nagumo model is used, as a model capable of describing the main features of a biological neuron and, at the same time, is computationally relatively simple. The results obtained are verified numerically. As a result, it was shown that there is no rectilinear dependence of the period of passage of the pulse along the ring on the number of neurons in the ring. Criteria for determining local bifurcations are also obtained.
KeywordsFitzHugh-Nagumo system, time delay, neural networks, stability, Hopf bifurcations.
