The paper considers the formation оf coherent structures in а population of excitable systems driven by noise. We focus оn two effects. (i) A one-dimensional lattice with аt least one inhomogeneous unit demonstrates noise-induced excitation waves. The degree оf coherence in such а spatial structure саn be enhanced by tuning the noise intensity. (ii) A random distribution оf the parameters responsible for the excitatory properties and the interaction strength leads to self-organization in the form of cluster synchronization.
