摘要: We study the propagation of periodic pulse trains in excitable media exposed to external spatio-temporal noise using the light-sensitive Belousov-Zhabotinsky reaction with underlying Oregonator model as representative example. In weak noise approximation we find noise-induced transitions dispersion relation trains. discuss noise-enhanced of pulse within a certain wave-length range caused by moderate strength.
