我们利用奇异摄动理论分析了一维突触耦合神经网络中N个弱相互作用脉冲的动力学行为。该网络的非局部积分微分方程,其中的积分内核表示突触权重的空间分布,和神经元的输出活动被视为一个平均放电率。我们推导出一组N耦合的常微分方程(ODE)的动态的个人脉冲,建立一个直接的关系之间的明确形式的脉冲相互作用和结构的远程突触耦合。常微分方程系统被用来探讨平稳N脉冲和行波列的存在性和稳定性。
We use singular perturbation theory to analyze the dynamics of N weakly interacting pulses in a one-dimensional synaptically coupled neuronal network. The network is modeled in terms of a nonlocal integro-differential equation, in which the integral kernel represents the spatial distribution of synaptic weights, and the output activity of a neuron is taken to be a mean firing rate. We derive a set of N coupled ordinary differential equations (ODEs) for the dynamics of individual pulses, establishing a direct relationship between the explicit form of the pulse interactions and the structure of the long-range synaptic coupling. The system of ODEs is used to explore the existence and stability of stationary N-pulses and traveling wave trains.
