Chemical wave based programming in reaction-diffusion systems
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.
