[Method of determining visual pigments in situ and their study in some vertebrates].
A simple electrophysiological method for determining of visual pigments in isolated retina is described. The method is based on registration of the early receptor potential amplitude which is proportional to the visual pigment content and on measurement of the rate of the decrease of this amplitude under the action of the bleaching light of a known wavelength and intensity. The results of the determining of rod and cone visual pigments in the lamprey Lampetra fluviatilis, teleosts Diplodus annularis and Trachurus mediterraneus ponticus, toad Bufo bufo and guinea pig are presented.
