【Abstract】 Based on weighted neuron model with the attack strategy,the self-organized criticality behavior is studied. In the model,the mechanism of integrate and fire of Olami-Feder-Christensen(OFC) model,which is similar to the mechanism of neuron model,is used.The weighted scale free network is introduced to simulate the brain, and to study the topology structure and effect on the SOC behavior.With the consideration of the aging in the brain,the topology structure and SOC behavior under the attack strategy are also investigated.更多还原
