摘要: Pre-Bötzinger复合体是新生哺乳动物呼吸节律起源的关键部位,是呼吸节律产生的中枢。本文以pre-Bötzinger复合体中两个耦合的神经元为研究对象,并考虑钙离子动力学的耦合神经元模型。利用快慢动力学和分岔分析,研究混合簇同步放电模式及其产生机制。结果表明钙离子的周期性波动对混合簇放电模式的产生有极大的影响,钙离子的波动及分岔曲线相对位置的改变是混合簇放电产生的主要原因。
Abstract: The pre-Bötzinger complex is a kernel part in brainstem region that generates respiratory rhythm, and it is the center in control of respiratory pattern in mammals. In this paper, based on the Butera model, two-coupled neuron networks including the dynamics of calcium ion in the Pre-Bötzinger complex are studied. The generation mechanism and synchronous discharge of mixed bursting are studied. The results show that periodic fluctuation of calcium ions has a great influence on the generation of the mixed bursting, so as the relative position of bifurcation curves.
