摘要： 神经网络的持续震荡对生物认知功能有重要作用。本文以化学突触方式耦合的单向纯环网络为研究对象,从两方面分析单脉冲周期传播的稳定性:一方面,是在给定系统参数条件下,对初态的吸引域;另一方面,是在特定初态条件下,对系统参数的吸引域。之后根据所得分析结果,提出2种促进周期传播的方法和一种抑制的方法。其中,利用2次间隔刺激同一神经元的物理机制可能对理解生物实验中的回响现象有启示作用。

Abstract: Sustained activities are important to cognitive functions in neuroscience. The stability of one single firing signal propagating periodically in a neural loop coupled by chemical synaps-es(Tsodyks - Uziel - Markram model) is investigated in two ways. One is toinvestigate the initial statebasin of attraction under given system parameters;the other is to investigate the system parameter basin of attraction under one special initial condition. Based on the above results, two practicable approaches to promote periodic propagation stable, and one approach to inhabit propagations were propesed. The results of the two stimulations on one neuron approach may give hints to understand the reverberatory in biological experiments. These researches are important to understand the functions of loops in neural networks.

Key words: biological neural network, chemical synapse, loop, periodic propaga-tion, basin of attraction, Tsodyks-Uziel-Markram model
