Dynamics of changes in the electroretinogram of isolated frog and turtle retinas during rhythmic photic stimulation in conditions of induced lipid peroxidation

Comparative study of isolated retinas of frogs and turtles exposed to rhythmical photostimulation was conducted. It was shown that there are marked differences between the responses of isolated retinas of frogs and turtles to the rhythmical photostimulation. A considerable depression of the total amplitude of the rhythmical electroretinogram was observed under the conditions of induced lipid peroxidation. Introduction of a selenium compound to the superfusing medium increased to a certain extent both the single and rhythmical responses of isolated retinas of the animals.
