摘要
In this paper, a general artificial neural network model is studied for four neurons with bidirectional time delayed connections between the neurons. We try to find out some critical condition under which synchronous periodic oscillation occur when the parameters of the networkmodel pass through some critical values. We present a detailed discussion about synchronous periodic solution of the network by employing the perturbation-incremental scheme. The synchronous periodic solution arising from Hopf bifurcation due to time delay is analytically given, at the same time, the necessary and sufficient condition for the synchronous periodic solution are also obtained. The results obtained in this paper give an explicit view of the dynamics of the delayed neural network. It can be seen that theoretical analysis is in good agreement with the numerical simulation, which shows that the obtained result is correct. To our knowledge, obtaining analytically synchronous periodic solution by employing the perturbation-incremental scheme is new in the literature.
