Discharge and Synchronization of Coupled Chay Neuron Model Under Electromagnetic Field
When the membrane potential of neurons fluctuates,complex time-varying elec-tromagnetic fields are generated in the nervous system,and this induced electromagnetic field will further regulate the firing activity of neurons.Considering that neurons are affected by electromagnetic induction,the improved four-dimensional Chay neuron system is obtained by adding external stimulus current and magnetocontrolled memristor into the classical three-dimensional Chay neuron model.Using MATLAB software to simulate the single-parameter and double-parameter bifurcation diagrams of the system,it can be observed that the system will be affected by a variety of parameters,and with the change of parameter values,it will show a rich dynamic behavior.On this basis,the synchronization of the system under the ac-tion of magnetic flux coupling strength is studied,and it is found that increasing the coupling strength can promote the complete synchronization of the system under certain conditions.The improved neuron model has more bifurcation parameters and considers the influence of electromagnetic induction in cells,which provides theoretical reference for studying the influ-ence of external electromagnetic radiation on neurons.
