Reconstruction of the slow PIII from the rod potential.

Abstract

Light-induced changes in K+ efflux across the photoreceptor membrane are compensated for by active uptake of K+ by a pump, which works with a time lag causing changes in [K+]o termed the KRG. From aspartate-treated bullfrog retinas we isolated the rod potential and the slow PIII, and by using them as indices of rod function and the KRG, respectively… (More)
