Pulse Stimulation Of Coupled Chemical Oscillators

Stimulated single and coupled reaction cells serve as well defined models of behaviour of dynamical regimes of biological cells and tissues. Results of experimental and theoretical studies of responses to single and periodic pulse stimulations of an oscillating open (flow-through) reaction cell were discussed in earlier papers [1, 2]. It was demonstrated that single pulse stimulation can cause both positive and negative phase shift of concentration oscillations. The phase transition curves (PTC), i.e. The dependence of the new (shifted) phase of the oscillation on the phase when the stimulation has been applied, were constructed from experimental data. For strong stimulations PTC s were of the topological type “0” and for weak stimulations of the type “1” [2].
