Objective To study the complex dynamical behavior of HR neuron. Methods The influence of external current on the firing patterns was investigated with the method of nonlinear dynamics. Especially,based on fast-slow analysis,the generation mechanism of bursting and firing rhythm was explored. Results Numerical simulation revealed the different parameter domain for bursting and spiking individually. In addition,the structure of bifurcation sequence was obtained. Conclusion This study is instructive for understanding the role of outside stimulus played in complex neuron activities.
