An example of computer simulation: The mode transition evoked by short depolarization.
(a) Time course of membrane potential. Horizontal thick bar: current pulse (-0.5 nA, 2s) is applied.
(b) Time course of [Ca²⁺]_in corresponding to (a).
(c) Projection onto the ([Ca²⁺]_in-V) plane of the trajectories corresponding to the strange attractor and the limit cycle from (a) and (b). The arrow indicates to the direction of increasing time.
