摘要: The effect of intercellular coupling on the switching between periodic behavior and chaos is investigated in a model for cAMP oscillations Dictyostelium cells. We first analyze dynamic homogeneous cell population which governed by three‐variable differential system bifurcation diagrams are obtained as function two control parameters. then consider mixing populations behaving chaotic manner, respectively. Cells coupled through sharing common chemical intermediate, extracellular cAMP, controls its production release cells into medium; dynamics mixed suspension five‐variable system. When differ value single parameter measures activity enzyme that degrades diagram established can be used to predict behavi...
