For mammals, respiration movement is an essential life process that plays a key role in keeping proper body function and survival. The pre-B?tzinger complex in the ventrolateral medulla is a central part of mammals that generates and regulates respiratory rhythm. In this paper, we use the fast-slow decomposition and bifurcation analysis to investigate the effects of inositol triphosphate concentration on dendritic mixed bursting of the two-coupled pre-B?tzinger complex neurons. The research indicates that inositol triphosphate concentration significantly affects both bursting pattern and periodic of the dendritic mixed bursting. Furthermore, we also reveal the dynamical mechanisms underlying the generation and transition of dendritic mixed bursting.
