【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 th e 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.
