摘要

Developmental aspects of the distribution of FMRFamide (Phe-Met-Arg-Phe-NH2) immunoreactivity (ir) were investigated by indirect immunofluorescence in the brain, pituitary and terminal nerve of the frog, Rana esculenta. Soon after hatching. FMRFamide neurons were found in the proximal terminal nerve, mediobasal olfactory bulb, caudal dorsolateral pallium, diagonal band of Broca, anterior preoptic area, suprachiasmatic area, thalamus, infundibulum, and developing pituitary. FMRFamide fibers were present in the olfactory epithelium, terminal nerve, olfactory bulbs, dorsal and midventral telencephalon, epiphysis, mediolateral thalamus, pretectal gray, optic tectum, infundibulum, posterior interpeduncular nucleus-tegmentum area, and rostral rhombencephalon. During successive developmental stages, ir neurons were no longer observed in the dorsal telencephalon and pituitary. In late larval stages, ir neurons appeared in the medial septal area, and ir fibers in the cerebellum and torus semicircularis. At the same time, the frequency of ir neurons increased progressively in the anterior preoptic area, suprachiasmatic area and infundibulum. FMRFamide-ir neurons were never revealed in mesencephalon and rhombencephalon. Numerous ir fibers terminated in the median eminence and intermediate lobe of the pituitary. The adult pattern of distribution of FMRFamide-ir elements in the brain was achieved during the postmetamorphic development. In light of the existing literature, the possible placodal origin of forebrain-located FMRFamide neurons is briefly discussed.
