有界噪声激励下神经系统中反随机共振现象研究
Inverse Stochastic Resonance in Neural System Induced by Bounded Noise
摘要
Abstract
In order to study the effect of noise on the information transmission in neural system,firing of neural system driven by the bounded noise was discussed,especially the inhibitory effect of neuron fir-ing,which was called the phenomenon of inverse stochastic resonance.Through the stochastic simula-tion method of Monte Carlo,the influence of parameters of bounded noise on the average spiking rate was systemic studied when the neurons were in the continuous firing state under the input current.In-vestigation results indicate that random phase can restrain neural spiking and induce the phenomenon of inverse stochastic resonance.Meantime,the bigger the amplitude is,and the smaller the frequency is, the better of the inhibition on the neural spiking is.In addition,the smaller the current intensity is,the smaller the average spiking rate is and it is means that the inhibition effect is more distinct.The research of inhibitory effect gives an important theoretical significance on the treatment of medical diseases such as epilepsy.关键词
