Chemical Wave Based Programming in Reaction-Diffusion Systems
J. Gorecki and J. N. Gorecka

In this paper we discuss one of the methods in which information processing with excitable medium can be programmed. We demonstrate that information processing properties of a reaction diffusion medium can be controlled by a chemical signal composed of excitation pulses. The simplest “programmable” chemical signal processing device is a memory that can be loaded or erased by a pulse arriving from appropriate input channels. We discuss how chemical memory can be incorporated into more complex information processing devices like signal switches or programmable signal channels.
