We study the propagation of solitary waves in a discrete excitatory network of integrate-and-fire neurons. We show the existence and the stability of a fast wave and a family of slow waves. Fast waves are similar to those already described in continuum networks. Stable slow waves have not been previously reported in purely excitatory networks and their propagation is particular to the discrete nature of the network. The robustness of our results is studied in the presence of noise.
我们研究了积分发放神经元的离散兴奋性网络中孤立波的传播。我们展示了一种快波和一族慢波的存在性与稳定性。快波与连续网络中已描述的那些相似。稳定的慢波此前尚未在纯兴奋性网络中被报道过，并且它们的传播是该网络离散性质所特有的。我们在有噪声的情况下研究了结果的稳健性。
