Abstract
Using the Belousov‐Zhabotinsky (BZ) chemical system we explore the resonant response of spatially‐extended oscillatory and excitable media to periodic perturbation. Resonance in excitable media is particularly relevant to biological systems, where excitable dynamics (threshold response to stimulus and refractoriness) are common. Methods to quantify spatio‐temporal patterns will be discussed and the resonant patterns in excitable and oscillatory media will be compared. Experimental observations are compared to the results from numerical simulations of the Brusselator and FitzHugh‐Nagumo models and from a forced complex Ginzburg‐Landau amplitude equation.
