首先研究了噪声诱导的耦合发放神经元的完全同步和频率同步。噪声和耦合的影响进行了讨论。研究发现,爆发神经元比发放神经元更容易实现放电同步,这意味着爆发活动对神经元网络中的信息传递更重要。其次,研究了噪声对带噪声映射神经网络放电同步的影响。利用放电率函数和序指数研究了噪声诱导的同步和时序。共振频率的阈下刺激能显著增强兴奋性神经元的放电同步性和时序性。最后得出结论,随机扰动在神经元网络的放电活动和时序中起着重要的作用。
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.
