### Rich dynamics of the Oregonator model in animations

Reduced from the Field–Kőrös–Noyes mechanism for the Belousov–Zhabotinsky reaction, the Oregonator is based on five elementary stoichiometries and written (in scaled form) as:

The model exhibits many of the dynamic features found in the reaction.

Oscillations

Subcritical Hopf bifurcation

Excitability

Identical oscillators – in-phase oscillations

Identical oscillators – anti-phase oscillations

Nearly identical uncoupled oscillators

Nearly identical coupled oscillators – anti-phase oscillations

Nearly identical coupled oscillators – in-phase oscillations

Nearly identical coupled oscillators – oscillator death
