The time-varying electromagnetic field in the media could be formed when there is a fluctuation in the concentration of charged ions across the membrane of neurons. The electrical activities of neurons will be affected by the electromagnetic field. In this paper, the effect of positive and negative field coupling on the wave propagation in the regular network is discussed. The mechanism for how the wave propagation is modulated by the field coupling will be explored in detail. It is found that different firing pattern could be detected under different conditions. The results state that the collective dynamical behaviors of membrane potential of neurons could be regulated and suppressed by positive filed coupling, but not affected by negative field coupling. The potential mechanism is that the frequency of electrical activities will have a distinct change due to the frequency of magnetic flux has a distinct change, and these two frequencies keep pace. Furthermore, the bifurcation analysis of single neuron and stability of coupled neurons network are discussed with different magnetic flux initial values selected. Then the synchronization statistical parameter confirm that positive field coupling could promote realization of synchronization.

场耦合对神经网络中波传播的影响

当跨神经元膜的带电离子浓度发生波动时,可以在介质中形成随时间变化的电磁场。神经元的电活动将受到电磁场的影响。本文讨论了正负电场耦合对规则网络中波传播的影响。将详细探讨如何通过场耦合调制波传播的机制。发现在不同条件下可以检测到不同的点火模式。结果表明,通过正场耦合可以调节和抑制神经元膜电位的集体动力学行为,而不受负场耦合的影响。潜在的机理是,由于磁通量的频率具有明显的变化,因此电活动的频率将发生明显的变化,并且这两个频率保持同步。此外,讨论了单个神经元的分叉分析和耦合神经元网络的稳定性,并选择了不同的磁通量初始值。然后,同步统计参数证实正场耦合可以促进同步的实现。
