The information transfer of neuronal network is closely related to the coupling synchronization dynamics of multiple neurons. Numerous studies show that the coupling synchronization problem of neuronal is crucial for the process of brain processing information. In this paper, the complex discharge of neurons is studied based on a threedimensional hybrid neurons model, the model is composed of the fast subsystem of Wilson model and the slow subsystem of HindmarshRose model. Despite its simplicity, the model is capable of reproducing a range of dynamical behaviors commonly observed in regular spiking, fast spiking, continuous bursting, and intrinsic bursting cells. Based on the three-dimensional hybrid neuron model, this paper explores the synchronous discharge behavior of two neurons under three different types. Explore the different firing states of neurons under different coupling intensities, and compare the synchronous firing states of two neurons through phase difference. This study will provide guidance and help for people to further understand the mechanism of neurological diseases, and provide2 possible research ideas in the field of neuroscience.
