The onset of regular bursts in a group of irregularly bursting neurons with different individual properties is one of the most interesting dynamical properties found in neurobiological systems. In this paper we show how synchronization among chaotically bursting cells can lead to the onset of regular bursting. In order to clearly present the mechanism behind such regularization we model the individual dynamics of each cell with a simple two-dimensional map that produces chaotic bursting behavior similar to biological neurons.
在一群具有不同个体特性的不规则爆发神经元中出现规则爆发,是神经生物学系统中发现的最有趣的动力学特性之一。在本文中,我们展示了混沌爆发细胞之间的同步如何导致规则爆发的出现。为了清晰地呈现这种规则化背后的机制,我们用一个简单的二维映射对每个细胞的个体动力学进行建模,该映射产生类似于生物神经元的混沌爆发行为。
