Effects of Deterministic Waves and Small-World Connectivity on the Noise-Induced Spatial Dynamics of Excitable Media.
M. Perc

We investigate how subthreshold deterministic waves and introduction of small-world connectivity affect the inherent spatial frequency of noise-induced patterns in an excitable media. We find that the deterministic waves are unable to impose a non-eigen spatial frequency on the media, whilst the small-world coupling altogether hinders the noise-induced pattern formation. Both findings are briefly discussed in view of their biological importance.
Key words: excitable media, noise, deterministic forcing, small-world network
