  • Title: Suppression of chaos by periodic oscillations in a model for cyclic AMP signalling in Dictyostelium cells.
    Author: Li Y, Halloy J, Martiel JL, Wurster B, Goldbeter A.
    Journal: Experientia; 1992 Jun 15; 48(6):603-6. PubMed ID: 1319352.
    Abstract:
    We investigate how the introduction of cells oscillating periodically affects the behaviour of a suspension of Dictyostelium discoideum amoebae undergoing chaotic oscillations of cyclic AMP. The analysis of a model indicates that a tiny proportion of periodic cells suffices to transform chaos into periodic oscillations in such suspensions. A similar result is obtained by forcing the aperiodic oscillations by a small-amplitude, periodic input of cyclic AMP. The results provide an explanation for the observation of regular oscillations in suspensions of a putatively chaotic mutant of Dictyostelium discoideum. More generally, the results show how chaos in biological systems may disappear through the coupling with periodic oscillations.
