Abstract

Abstract

The rhythmic movement was a spontaneous behavior generated by central pattern generator (CPG). At present,the CPG model only showed the spontaneous behavior,it did not refer to the instruction regulation role of cerebral cortex. A revised model based on Matsuoka Neural oscillator theory was presented to better show the regulation role of cerebral cortex signal to CPG neuronal network. The complex interaction between input signal and other parameters in CPG network was established,making the every parameter of CPG itself vary with the input signal. It enhanced the effect of input signal to CPG network to make the CPG network express the self-regulation movement state instead of being limited to the spontaneous behavior,reflecting the regulation role of cerebral cortex signal. The numerical simulation showed that the revised model could generate various movement forms with different modes and frequencies,and their interchanges. It was theoretically revealed that the cerebral cortex signal could regulate the mode and frequency of gait in the course of gait movement.
