Traveling waves of excitation provide for communication and                spatial organization in a variety of biological systems.  The                   long term goal of this project is to study mathematically the                   origin and properties of travelling waves of excitation in heart                muscle, cerebral cortex, fields of aggregating cells, and in                    nonliving chemical mixtures.  The general method is first to                    build a realistic mathematical model of the specific system, then               to determine the properties of the model by analytical methods,                 and finally to compare the behavior of the model with observed                  properties of excitation waves in the specific  system.  The                    proposal emphasizes those features of wave propagation that are                 common to all excitable media  because of their similar                         mathematical description.  At the same time, the best current                   scientific understanding of specific mechanisms is built into the               models, so that a detailed quantitative comparison between theory               and experiment can be sought.  These studies have indirect                      medical relevance because some physiological pathologies are                    associated with classical migraine (waves of spreading                          depression).
