Abstract

Noise-induced complete synchronization and frequency synchronization in coupled spiking and bursting neurons are studied firstly. The effects of noise and coupling are discussed. It is found that bursting neurons are easier to achieve firing synchronization than spiking ones, which means that bursting activities are more important for information transfer in neuronal networks. Secondly, the effects of noise on firing synchronization in a noisy map neuronal network are presented. Noise-induced synchronization and temporal order are investigated by means of the firing rate function and the order index. Firing synchronization and temporal order of excitatory neurons can be greatly enhanced by subthreshold stimuli with resonance frequency. Finally, it is concluded that random perturbations play an important role in firing activities and temporal order in neuronal networks.

摘要

首先研究了耦合放电和爆发神经元中的噪声诱导完全同步和频率同步。讨论了噪声和耦合的影响。结果发现，爆发神经元比放电神经元更容易实现点火同步，这意味着爆发活动对于神经网络中的信息传递更为重要。其次，研究了噪声对噪声映射神经元网络中点火同步的影响。通过点火率函数和顺序指数研究了噪声诱导的同步和时序。具有共振频率的亚阈值刺激可以大大增强兴奋性神经元的点火同步和时序。最后得出结论，随机扰动在神经元网络的点火活动和时序中起着重要作用。
