Abstract: Fluctuation of membrane potential occurs when the concentration of ions, e.g., Calcium, Potassium, Sodium, in the cell is changed. When external electric stimulus beyond threshold is applied, action potential can be induced to predict the changes in distribution density of ions, which can also trigger time-varying electric field and magnetic field. For example, each static charge can induce spatial distribution of electric field while any moving charge can generate distribution of magnetic field. In this paper, a neuron is considered as a complex charged body and the effect of electromagnetic field is considered to build a new neuron model, which magnetic flux and charges is used to describe the variation of magnetic field and electromagnetic induction, electric field, respectively. The physical neuron model is then described by dimensionless dynamical system after scale transformation and then is verified on analog circuit platform. Nonlinear analysis is practiced on this new neuron model and external electromagnetic radiation is applied to detect the mode transition and response in neuronal activities. The electrical activities can be modulated when the band of electromagnetic radiations is adjusted. It can throw light on investigation of neurodynamics and experimental practice in neural circuits.
