Abstract:
It is of great practical significance to consider the effect of electromagnetic radiation on neuron firing activity. In this paper, magnetic flux variable is introduced to describe the effect of external electromagnetic radiation on membrane potential, the magnetic flux e−HR neuron model is established, and the discharge characteristics and bifurcation modes of the system are discussed in detail. Based on the method of Matcont software programming simulation, the Hopf bifurcation behavior and coexisting discharge interval of the magnetic flux e−HR neuron model were studied, and it was found that the system had hidden discharge behavior.In addition, by analyzing bifurcation behavior on the two−parameter plane, it has been found that the system has bifurcation modes such as doubling period, inverse doubling period, with chaos plus period and without chaos plus period. Therefore, it provides a useful discussion for further understanding of the generation and bifurcation behavior of hidden discharge in magnetic flux neurons.
