【摘要】Based on an integrate-and-fire mechanism,we investigate self-organized criticality of a simple neuron model on a modified BA scale-free network with aging nodes.In our model,we find that the distribution of avalanche size follows power-law behavior.The critical exponent (τ) depends on the aging exponent α.The structures of the network with aging of nodes change with an increase of α.The different topological structures lead to different behaviors in models of integrate-and-fire neurons. 【总页数】6页(759-764)
