From simple to complex oscillatory behaviour

The study of biochemical oscillations thus extends in many directions, from simple and complex periodic behaviour to chaotic dynamics, and from cellular rhythms to chronopharmacology. It is the purpose of this book to explore the molecular bases of these oscillatory phenomena and the richness of their physiological implications. [Pg.27]

Within this restrictive framework of two-variable models, Albert Goldbeter derives fascinating original results such as birhythmicity, which allows a system to choose between two simultaneously stable oscillatory regimes. With the number of variables, the repertoire of dynamic phenomena increases rapidly. Now, besides simple periodic behaviour we can also predict and observe complex oscillations of the bursting type, the coexistence between more than two rhythms, or the evolution toward chaos. As the author shows, small variations in the values of some control parameters permit the switch from one mode of behaviour to the other. The essential elements, in all cases, are the feedback mechanisms of biochemical reactions and the fact that these reactions occur far from equilibrium. [Pg.627]
