Homogeneous and Spatio-temporal Chaos in Biochemical Reactions With Feedback Inhibition

A biochemical oscillator involving feedback inhibition can be extended to generate a chaotic attractor. The simple chaotic attractor may be exploited to create signals of higher dimension by passive forcing of other reactions. Diffusively coupled oscillators with negative feedback exhibit regular and irregular patterns in time and space associated with periodic and hyperchaotic attractors, respectively.
