Abstract:
An immunohistochemical study of the distribution of tyrosine hydroxylase has been performed in the retina of lizards of the genera Podarcis, Anolis and Tarentola. Immunoreactive cells extending their processes into the inner plexiform layer were observed in all three species. Reactive fibres in the outer plexiform layer were also seen in Podarcis and Anolis, and hence they possess not only amacrine but also catecholaminergic interplexiform cells. The retina of Anolis also showed reactive fibres aposed to the photoreceptors near the central fovea. The role of this outer retinal innervation on dopamine-dependent light-adaptive phenomena is discussed from a comparative perspective.
