title: Wavelength dependence of optical action potentials in the isolated rat atrium.
abstract: The wavelength dependence of optical action potentials was studied using voltage-sensitive merocyanine-rhodanine, merocyanine-oxazolone, and oxonol dyes in the isolated rat atrium preparation. Most of the dyes had action spectra that were similar to those reported in other preparations. Species-to-species difference was observed with a merocyanine-oxazolone dye.
