椭圆突发模型的电压区间映射

Voltage interval mappings for an elliptic bursting model

Jeremy Wojcik, Andrey Shilnikov

摘要:

我们采用Poincaré返回映射的参数区间的一个示例性的椭圆爆发模型,FitzHugh-Nagumo-Rinzel模型。使用的间隔映射,我们能够详细研究的分叉,背后的复杂活动之间的过渡:紧张尖峰和爆发,爆发和混合模式振荡,最后,混合模式振荡和静止的FitzHugh-Nagumo-Rinzel模型。我们说明了丰富的信息,定性和定量,这是来自庞加莱映射,神经元模型和类似的(电)化学系统。

英文摘要:

We employed Poincaré return mappings for a parameter interval to an exemplary elliptic bursting model, the FitzHugh-Nagumo-Rinzel model. Using the interval mappings, we were able to examine in detail the bifurcations that underlie the complex activity transitions between: tonic spiking and bursting, bursting and mixed-mode oscillations, and finally, mixed-mode oscillations and quiescence in the FitzHugh-Nagumo-Rinzel model. We illustrate the wealth of information, qualitative and quantitative, that was derived from the Poincaré mappings, for the neuronal models and for similar (electro)chemical systems.
