Abstract
A model is proposed of the pulse frequency modulation process in those neural systems where the neuron discharge is random. The model is characterized by one property, namely input-invariance of the output random process after a time transformation, which, on the one hand, greatly simplifies its analytical treatment, and on the other hand, gives a tool to determine experimentally whether the model describes the external behavior of a given neural system. The main dynamical properties of the model are studied, and the relevance of the results to information transmission by neural systems is discussed.
摘要
提出了一个适用于神经元放电具有随机性的神经系统中脉冲频率调制过程的模型。该模型具有一个特性，即在时间变换后输出随机过程的输入不变性，这一方面极大地简化了其分析处理，另一方面提供了一种通过实验来确定该模型是否描述给定神经系统外部行为的工具。研究了该模型的主要动力学特性，并讨论了这些结果与神经系统信息传输的相关性。
