Regular and chaotic oscillations in a system composed of two coupled, drastically different FitzHugh - Nagumo elements
A dynamic model of inferior olive neurons possessing periodic relaxation oscillations below the excitation threshold is proposed. The model is a system of two linearly coupled, drastically different FitzHugh - Nagumo elements. In the absence of coupling one element is in excitable mode and the other one exhibits periodic relaxation oscillations. We have shown that dynamics of the system can be described with onedimensional Poincare map. We were interested in regimes which have the prototypes in real electrophysiological experiments. We have established, that model shows a good qualitative agreement with experimental data obtained in inferior olive neurons.
