  Coupled nonlinear oscillators can exhibit a wide variety of patterns. We
study the Brusselator as a prototypical autocatalytic reaction diffusion model.
Working in the limit of strong nonlinearity provides a clear timescale
separation that leads to a canard explosion in a single Brusselator. In this
highly nonlinear regime it is numerically found that rings of coupled
Brusselators do not follow the predictions from Turning analysis. We find that
the behavior can be explained using a piecewise linear approximation.
