In experimental systems, when a spatially extended state becomes unstable by the increase of some control parameter, the new stable state may grow in different ways. It may grow globally from the noise that is always present in macroscopic systems, or it may propagate from special spatial locations such as impurities, nonuniformities, boundaries, and so on.
