Abstract:
It is a well established fact that noise may induce a coherent behavior in many kinds of systems: chemical reactions, biology and physical systems among them. For the particular case of excitable systems we have previously shown through an analytical theory that any source of disorder can play such a constructive role. The only important ingredient is the existence of a source that disorders the state of the system consituents.
In this work, we show which is the influence of the existence of repulsive interacting links in an excitable system. We also compare our results with the theory previously developed. It is found that an optimum amount of heterogeneity is needed such that the system shows the most coherent behavior.
