脉冲耦合振荡神经元的集体行为已被广泛研究。然而，在许多情况下，真正的神经元本质上不是振荡的，而是可兴奋的。可兴奋神经元网络有其特有的动力学特征，从功能组装的角度来看，它们也很有趣。本文用相位描述的方法研究了脉冲耦合可兴奋神经元的集体行为。结果表明，在可兴奋的漏积分-火神经元和离散时间Nagumo-Sato神经元网络中可以实现完全同步。解释了外部尖峰输入、内部状态衰减和反馈尖峰的协同作用。还报道了耐火度和噪声增强同步的方法。
Collective behavior of pulse-coupled oscillatory neurons has been investigated widely. In many cases, however, real neurons are intrinsically not oscillatory but excitable. The networks of excitable neurons can have their own characteristic dynamics, and they are of interest also from the viewpoint of functional assemblies. In the present paper, the collective behavior of pulse-coupled excitable neurons has been investigated using phase description. It is shown that full synchronization is achieved in networks of excitable leaky integrate-and-fire neurons and discrete-time Nagumo-Sato neurons. The cooperative roles of external spike inputs, decay of internal states, and feedback spikes are explained. Enhancement of synchronization by refractoriness and noise is also reported.
