Abstract

Serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) levels were determined in the visual Wulst, optic lobes, retina, cerebellum and brainstem of the pigeon during embryonic and posthatching periods. 5-HT content increased during development in almost all regions. 5-HIAA content generally showed the highest values within the second posthatching week and then decreased to reach adult values. The high 5-HT turnover (as indicated by high (5-HIAA/5-HT ratio) observed over the first posthatching week suggests a possible role of 5-HT on developmental processes which occur in pigeon visual areas over the same time.
