Abstract
It is shown that an arbitrarily weak (frozen) heterogeneity can induce global synchronized oscillations in excitable media close to threshold. The work is carried out on networks of coupled van der Pol-FitzHugh- Nagumo oscillators. The result is shown to be robust against the presence of internal dynamical noise. ©2001 The American Physical Society.File in questo prodotto:
