pubmed:abstractText
The diencephalon of nonmammalian vertebrates contains aminergic perikarya situated beneath the ependyma lining the third ventricle, known as the paraventricular organ (PVO). Catecholamines were visualized in the goldfish forebrain by formaldehyde-glutaraldehyde-induced fluorescence. Neuronal somata containing catecholamines were found in three paraventricular nuclei--the nucleus recessus posterioris (NRP), the nucleus recessus lateralis (NRL), and the nucleus posterioris paraventricularis (NPPv)--which may be considered to constitute the PVO of the goldfish. Lesion-degeneration investigations were conducted to determine whether the PVO contributes to the innervation of the goldfish pituitary. Following electrothermic lesions of the NRP, degenerating axons and nerve terminals were observed in the rostral pars distalis and in the proximal pars distalis, but not in the neuro-intermediate lobe of the pituitary. Following lesions of the NRL or of the NPPv, degenerating axons and nerve terminals were observed in the rostral pars distalis, the proximal pars distalis, and in the neurointermediate lobe. These observations demonstrate that the PVO is a source of pituitary afferents in the goldfish and suggest that the PVO is a source of the catecholaminergic innervation of the teleost pituitary.
