D. Theory of excitable media. Excitability and spatial order in membranes of developing systems
Abstract
A simple biological model of metabolic activities on membranes is explored with respect to excitability and spatial gradient formation. The model is shown to have the property of undergoing a phase transition from a non-excitable to an excitable condition. Once excitable, it is shown that a spatially-stable gradient can be formed on the membrane. Periodic gradients can be formed by a slightly modified process.
