Multi-stability involved mixed bursting within the coupled pre-Bötzinger complex neurons Project supported by the National Natural Science Foundation of China (Grant No. 11472009), Construction Plan for Innovative Research Team of North China University of Technology (Grant No. XN018010), and Scientific Research for Undergraduate of North China University of Technology. |
(color online) (a) Fast-slow decomposition analysis of the fast subsystem with gK = 5.2 nS (red), 5.92 nS (blue), and 7.5 nS (green) respectively. (b) Two-parameter bifurcation with parameters gK and h. The black curve represents the Hopf bifurcation curve, the red curve represents the fold bifurcation of equilibrium, and the blue curve represents the fold bifurcation of limit cycles. CP is the codimension-2 cusp bifurcation. |
