Immunocytochemical localization of putative cholinergic neurons in the goldfish retina.
The presence of putative cholinergic neurons in goldfish retina was demonstrated by immunocytochemical localization of choline acetyltransferase (ChAT), the synthesizing enzyme for acetylcholine. Four populations of ChAT-immunoreactive neurons were localized: two with cell bodies in the inner nuclear layer and two with cell bodies in the ganglion cell layer. The processes of these neurons ramified in lamina 2 and/or 4 (of 5) in the inner plexiform layer. These cell populations are comparable to populations of putative cholinergic neurons that have been identified by [3H]choline uptake [3, 10].
