Abstract
The dynamics of phase disturbances in the 1D uniform medium described by FitzHugh-Nagumo equations was studied. It was found that the system synchronizes its oscillations if the initial disturbances are small. Large disturbances resulted in the appearance of phase breaks. Depende nt on the system parameters, phase breaks were found to be either stab le or unstable; stable breaks led to target pattern-like sources, unst able to extended chaos.
