相对阈值耦合的混沌神经元同步研究

Synchronization in a chaotic neuronal map with relative threshold coupling

提出了混沌控制的相对阈值耦合方法,并将该方法用于混沌神经元团簇的控制上.仿真结果表明,混沌神经元团簇输出表现出显著的聚类性,相对阈值耦合方法中神经元的状态只与相邻的神经元有关,耦合的阈值和弛豫时间对控制结果有影响,阈值越小,达到同步的时间越短,弛豫时间越长,神经元聚类性越明显.

A relative threshold coupling method is proposed to control chaos of chaotic neuron and a coupled chaotic neuronal map is constructed. The simulation results show that the spatial behavior of the threshold coupled chaotic neuronal map can be synchronized. The outputs of each neuron are period as time evolution. The synchronization characteristic depends on the value of relative threshold and the relaxation time.
