Ring structures are widely used in neural networks,and previous research with respect to neural dynamic bifurcation were confined to models with single-ring structure.Notably,neural networks are composed of thousands of neurons coupled together,and these structures are so complex that they cannot be accurately described through only a single-ring structure,and therefore is more practical for investigating neural network models with multiple ring topology.In this paper,an asymmetric model with double-ring neural structure is proposed,and the stability and Hopf bifurcation of the model are investigated.Numerical simulations are subsequently actualized to corroborate the theoretical results.
