[The effect of acetylcholine on the membrane potential of goldfish retina horizontal cells and the frog electroretinogram].
The effect of acetylcholine was studied as applied to horizontal cells of the goldfish retina and frog electroretinogram ACh (1-10-9--1-10-3 M) depolarized the cells. The highest level of depolarization never reached the O-level of the membrane potential and was approximately equal to the membrane potential in the dark. ACh (1-10-2--5-10-2 M) inhibited b- and d-waves and revealed the stable PIII component. It is supposed that ACh may be a transmitter in retinal outer synpatic layer.
