CHAOTIC BEHAVIOR OF AN ACETYLCHOLINESTERASE ENZYME-SYSTEM

A two compartments model of an acetylcholinesterase enzyme system is i nvestigated. The model is used to investigate the bifurcation, instabi lity and chaotic behaviour of the system. The investigation has uncove red a good part of the rich dynamic characteristics of this system, in cluding: period doubling sequence leading to chaos, banded chaos, full y developed chaos, interior crisis, tangent bifurcation leading to int ermittency, periodic windows interrupting chaotic regions and alternat ing periodic chaotic sequences. The results relate to the phenomena oc curring in physiological experiments, such as the periodic stimulation of neural cells and the non-regular functioning of acetycholine recep tors.
