随机Chay神经元模型的自共振

Coherence of Stochastic Chay Neuron

本文对具有白噪声的Chay神经元模型的共振进行研究。白噪声被加到慢变量中相当于钙离子的波动。这是更具有生理意义的。随着噪声强度的增加,我们发现在某一优化噪声水平,信噪比经过极大值,这意味自共振的发生。同时,我们也证实了钙离子的波动可以引起信号的探察和转换。

In this paper, coherence of the Chay neuron with white noise is studied. White noise, which is added to show variable amounts to fluctuation of Ca2 + ionic. It is biologically reasonable, with the strength of noise increasing; it is observed that signal to noise ratio (SIVK)reaches a maximum at certain optimal noise level, which means the occurrence of coherence. At the same time, we prove that fluctuation of Ca2+ ionic can lead to the exploration and transudation.
