Electrical Activity Response Of A Neuron Under Electromagnetic Induction

The basic functions of the nervous system are mainly to receive,integrate and transmit information,including signal transduction within cells and information transmission between cells,while neurons are the basic structure and functional units of the nervous system.Neurons have always been a hot topic in scientific research.In practice,neurons are in a very complex environment and affected by various external stimuli and neighboring neurons,but they can still coordinate the nervous system,adapt to various complex biological environments and make the body function normally.In order to simulate the adaptive mechanism of neurons,we add a variety of external stimuli to different neuronal models to study the dynamic responses of neurons under the influence of electromagnetic induction and noise.Firstly,based on the Fitzhugh-Nagumo myocardial cell model,magnetic flux is used to describe electromagnetic radiation to study the transformation of electrical activity mode.In the presence of electromagnetic radiation,appropriate dynamic and functional responses can be observed in the sampling time series of membrane potential by setting different parameters of membrane potential feedback modulation.Then the electromagnetic radiation is added to the Hodgkin-Huxley neuron model,the magnetic flux is used to describe the electromagnetic field effect,the memristor is used to realize the membrane coupling,and the noise is added to study the firing activity and random response of the neuron.The multimodal discharge activity of neurons is related to the memory effect and adaptation of neurons.Then,based on the Hindmarsh-Rose neuron model,the high frequency and low frequency signals are simultaneously applied to the neurons,and the amplitude,frequency and phase of the mixed signals are changed,respectively,and the firing behavior of the neurons will occur in multiple modes.Furthermore,based on Helmholtz theorem,the Hamiltonian energy of the system is calculated to prove the dependence of energy on the mode selection of neuronal discharge activity.Finally,based on the degenerate optical parametric oscillator model,the cluster discharge behavior of the model parameters is adjusted,and the distribution of Lyapunov exponent is calculated in two parameter regions,and different discharge modes are induced by changing the amplitude of the input field.Finally,noise is added to study the transition between subharmonics and fundamental waves of degenerate optical parametric oscillators,which helps to understand the potential mechanism of the transition between electrical modes of neurons induced by electromagnetic radiation.
