Excitable Chemical Reaction Systems

Well defined and thoroughly studied chemical reaction systems such as the Belousov-Zhabotinskii (BZ) reaction  often enable a comparison of experimental results with the results of modelling both in oscillatory and excitable systems [2, 5, 8]. In this paper we make an attempt to demonstrate that properties of distributed forced excitable BZ systems can be understood on the basis of the response of the corresponding lumped parameter system (CSTR) to a single or periodic pulse forcing. We introduce an experimental technique for the construction of the phase excitation curve (PEC), based on double pulse experiments and demonstrate its use for the modelling and interpretation of the dynamical response of excitable systems to external forcing.
