Parametric pattern selection in a reaction-diffusion model

Stich, Michael, Ghoshal, Gourab and Perez-Mercader, Juan (2013). Parametric pattern selection in a reaction-diffusion model. PLoS ONE, 8 ,


We compare spot patterns generated by Turing mechanisms with those generated by replication cascades, in a model one-dimensional reaction-diffusion system. We determine the stability region of spot solutions in parameter space as a function of a natural control parameter (feed-rate) where degenerate patterns with different numbers of spots coexist for a fixed feed-rate. While it is possible to generate identical patterns via both mechanisms, we show that replication cascades lead to a wider choice of pattern profiles that can be selected through a tuning of the feed-rate, exploiting hysteresis and directionality effects of the different pattern pathways.
