神经元可以对外界电刺激作出适当的反应，并且可以仔细选择电活动的模式。大多数神经元模型主要强调嵌入膜的离子通道电流，理论模型可以产生电活动的性质。事实上，在神经元活动的模型设置期间，应该考虑一些物理效应。事实上，在细胞内离子浓度波动的过程中，感应电流和电场会引起膜电位的变化和带电离子的交换。因此，电磁感应的影响应予以认真考虑。本文提出用磁通量来描述电磁场的作用，基于物理单元一致性，通过输入感应电流，利用忆阻器实现膜上的耦合。噪声也被用来检测电活动和随机共振中的动力学响应，发现电活动中可以选择多种模式，并且可能与神经元的记忆效应和自适应有关。
Neurons can give appropriate response to external electrical stimuli and the modes in electrical activities can be carefully selected. Most of the neuron models mainly emphasize on the ion channel currents embedded into the membrane and the properties in electrical activities can be produced in the theoretical models. Indeed, some physical effect should be considered during the model setting for neuronal activities. In fact, induced current and the electrical field will cause the membrane potential to change and an exchange of charged ions during the fluctuation of ion concentration in cell. As a result, the effect of electromagnetic induction should be seriously considered. In this paper, magnetic flux is proposed to describe the effect of electromagnetic field, and the memristor is used to realize coupling on membrane by inputting induced current based on consensus of physical unit. Noise is also considered to detect the dynamical response in electrical activities and stochastic resonance, it is found that multiple modes can be selected in the electrical activities and it could be associated with memory effect and self-adaption in neurons.
