  We demonstrate that chimera behavior can be observed in nonlocally coupled
networks of excitable systems in the presence of noise. This phenomenon is
distinct from classical chimeras, which occur in deterministic oscillatory
systems, and it combines temporal features of coherence resonance, i.e., the
constructive role of noise, and spatial properties of chimera states, i.e.,
coexistence of spatially coherent and incoherent domains in a network of
identical elements. Coherence-resonance chimeras are associated with
alternating switching of the location of coherent and incoherent domains, which
might be relevant in neuronal networks.
