Abstract: The system composed of homology neural cluster and different neuron is regarded as the object in the paper.On the basis of biologic characteristic,a order parameter is founded and Fuke-Plank equation is used to describe the system order parameter,and then the system order parameter is used to extend the optimized response of homology neuron cluster,namely for resemble external stimulus,the homology neuron cluster predominates the different neurons by binding mechanism,optimizes the net architecture and realizes the optimized response to resemble external stimulus.The result can enhance the ability of representation to the external information.
