[Extracellular photoreceptor potential of albino rats].

In this study methodically simple model of mammalian's total rods photoreceptor potential obtained by the known methods of outside electrical activity suppression by barium ions and sodium aspartate is offered. The farmacological analysis of that potential with using of ions-blockers of the potential-dependent conductances demonstrated that the offered potential consisted of the same components as the known intracellular responses.
