Three views on the parameterized slow motion manifolds and the 2D nullcline in a 3D leech inter-heart neuron model. The blue curve consists of equilibria of the system. The zebra-like surface with two folds is comprised of the periodic orbits. It ends up at the homoclinic saddle-node bifurcation (SNIC in modern jargon). Shown in red are the co-existent bursting and tonic-spiking orbits.
