SOC Behavior of Simple Hierarchical Network
Xuewen Yan · Journal of Changshu Institute of Technology · 2012
The avalanche behavior of simple two-level network is studied by using the improved OFC model in this paper.Considering the different nature or function between levels,two different control parameters,and are introduced to express control parameters of level internal and levels respectively.The conclusion is reached that the avalanche distribution obeys the power-law distribution within a certain range.The system will not be in the self-organized critical state,but in the supercritical state when the parameters exceed the certain value.Otherwise,the power spectrum of time series of the average membrane potential approximately obeys the power-law behavior.
