电磁辐射背景下的神经动力学研究
Study on the Neural Dynamics under the Effect of Electromagnetic Radiation
摘要: 长期暴露在低频磁场下可能导致神经性疾病，本文基于考虑电磁辐射的Hindmarsh-Rose神经元模型，对电磁辐射背景下的神经发放行为进行了研究。电磁辐射作用效果支撑了包含单周期、多周期、复杂周期等多种神经发放模式。在传统的神经模型分岔分析中，外部刺激电流是决定神经发放模式的关键因素。我们的研究结果表明电磁作用效果与外部刺激电流共同决定神经发放模式，改变电磁作用效果能诱导神经发放模式转迁。这将有助于从理论上理解电磁作用效果在神经动力学行为中所起到的关键性作用。为预防和治疗电磁辐射相关的神经疾病提供理论启发。
Abstract: Long-term exposure to low-frequency magnetic fields may lead to neurological diseases. Based on the Hindmarsh-Rose neuron model considering electromagnetic radiation, the neuronal firing be-havior under the background of electromagnetic radiation was studied. The effects of electromag-netic radiation support a variety of nerve delivery modes including single periodic, multi-periodic and complex-periodic patterns. In the traditional bifurcation analysis of neural models, the external stimulus current is the key factor to determine the mode of neuronal firing. Our results show that the effect of electromagnetic interaction and external stimulus currents together determine the mode of neuronal firing. Changing the effect of electromagnetic interaction can induce the mode transition of neuronal firing. This will help us to understand theoretically the key role of electro-magnetic effects in neural dynamical behavior, and provide theoretical inspiration for the preven-tion and treatment of neurological diseases related to electromagnetic radiation.
