The se action potentials can be in the forms of a single transient spike\, a t ransient burst or a periodic burst. In this talk\, I will consider global and local invariant manifolds as the main organizing topological structure that explains the underlying mechanisms for the generation of such activi ties. First\, I will explain how a stable manifold of a saddle equilibrium causes a switching phenomenon in a single transient AP of a cerebellar st ellate cell model. Then\, I will introduce an algorithm for computing stab le manifolds of a saddle slow manifold using two-point boundary value prob lem and continuation methods. Finally\, I will show the role of this manif old in determining the dynamics of transient and periodic bursting. This i s joint work with Anmar Khadra\, Vivien Kirk and Hinke M.
