Emergent dynamic behaviors in function of β and δ in the DMN formed by two subsystems.

β: the past influence coefficient. δ: the level of the enzymatic covalent regulatory activity (threshold value). Each metabolic subsystem may present one of the following three states: on: the metabolic subsystem is always in an active state, on-off: the MSb always present cycles of activity-inactivity, off: The metabolic subsystem always presents an inactive state. Ch: deterministic chaotic behaviors. P: transitions between periodic and/or stationary behaviors. MSb1: metabolic subsystem 1. MSb2: metabolic subsystem 2.
