文摘The generation of spontaneous synchronized rhythm and its role are studied by using a globally coupled excitable stochastic neuronal network.When the coupling strength exceeds a critical value,the neurons with a suitable noise in the network exhibit a strong tendency to synchronize and display a spontaneous rhythm.The coherence of the network can be enhanced by a suitable noise and a coupling of the network.The spontaneous rhythm enhances the ability of the network in processing weak periodic signals.
