我们研究了图案的多节奏动力学的出现，这些图案是小的神经兴奋网络的基石，例如控制动物各种运动行为的中央模式发生器。我们发现，起搏器决定这样一个网络的具体节奏组成的现实霍奇金-赫胥黎型神经元的顺序参数，这是神经元的爆发持续时间或占空比的比率确定。我们分析了不同的配置的图案，并描述了协同的爆发模式的通用机制。我们还讨论了抑制性网络的多稳定性，导致其紧急同步行为的多节律性。(C)2008年美国物理学会。
We study the emergence of polyrhythmic dynamics of motifs which are the building block for small inhibitory-excitatory networks, such as central pattern generators controlling various locomotive behaviors of animals. We discover that the pacemaker determining the specific rhythm of such a network composed of realistic Hodgkin-Huxley-type neurons is identified through the order parameter, which is the ratio of the neurons' burst durations or of duty cycles. We analyze different configurations of the motifs and describe the universal mechanisms for synergetics of the bursting patterns. We discuss also the multistability of inhibitory networks that results in polyrhythmicity of its emergent synchronous behaviors. (C) 2008 American Institute of Physics.
