We study the stochastic-resonant synchronization properties of a ring of excitable FitzHugh?Nagumo cells, when nearest-neighbor units are coupled diffusively with strength E through their inhibitor fields. The system is submitted to a common subthreshold adiabatic signal and independent Gaussian white noises with common variance
