Phase-disorder-induced firing activity in excitable neuronal networks with attractive and repulsive coupling

摘要: It has been revealed that the network of excitable neurons via attractive coupling can generate spikes under stimuli subthreshold signals with disordered phases. In this paper, we explore firing activity induced by phase disorder in neuronal networks consisting both and repulsive coupling. By increasing fraction coupling, find that, weak strength case, threshold is increased system response to decreased, indicating effect inducing neuron weakened Interestingly, large see an opposite situation, where coupled show a rather even small disorder. The latter case implies enhanced A two-coupled used explain role on phase-disorder-induced activity.
