生物神经元是阈值装置的很好例子-这就是为什么神经系统在寻找随机共振（SR）和时空随机共振（STSR）现象的实现时处于胎儿中。在这封信中，一个简单的集成和火灾模型被用来证明STSR在神经元链的可能性。到目前为止的理论和计算模型表明，SR和STSR可以发生在神经系统中。然而，这些现象所起的作用有多重要以及它们对神经生物学的影响仍然是一个问题。因为SR和STSR的直接生物学证据似乎是一个坚韧的问题，人们可能会考虑间接的方法来确定内部噪音是否在神经系统中发挥了建设性的作用。一个神经元回路具有有趣的特征（频率选择），这可能为回答前一个问题提供线索。(C)2000由Elsevier Science B.

Biological neurons are good examples of a threshold device - this is why neural systems are in the fetus when looking for realization of Stochastic Resonance (SR) and spatio-temporal stochastic resonance (STSR) phenomena. In this Letter a simple integrate-and fire model is used to demonstrate the possibility of STSR in a chain of neurons. The theoretical and computational models so far suggest that SR and STSR could occur in neural systems. However, how significant is the role played by these phenomena and what implications might they have on neurobiology is still a question. Because the direct biological proof of SR and STSR seems to be a tough issue one might look at indirect ways to decide whether the internal noise plays My constructive role in the nervous system. A loop of neurons is shown to have interesting features (frequency selection) which might supply a clue for answering the previous question. (C) 2000 Published by Elsevier Science B.V.
