电磁辐射下神经元模型的放电行为分析

Analysis of Neuron Discharge Behavior under the Electromagnetic Radiation

摘要: 引入忆阻器以及磁通项改进了三变量Hindmarsh-Rose模型，改进后的电磁场神经元模型用来描述考虑电磁感应的神经元电活动的动力学行为，并且当外部电磁辐射作用到神经元上时，即加入噪声来研究神经元的放电活动和随机响应时，检测到神经元中电活动的多种模式。结果表明，外界刺激振幅较大时更容易产生簇放电模式。特别地，可以发现电活动模式可以交替出现。

Abstract: The introduction of memristors and flux terms improves the three-variable Hindmarsh-Rose model, and the improved electromagnetic field neuron model is used to describe the dynamic behavior of the electrical activity of neurons considering electromagnetic induction, and when external elec-tromagnetic radiation acts on the neurons, that is the noise is added to study the firing activity and random response of the neuron, multiple patterns of electrical activity in the neurons are detected. The results show that the discharge mode of bursting is more likely to occur when the external stimulus amplitude is larger. Particularly, it can be found that multi-mode electrical activity can occur alternately.
