The distribution of neuropeptide Y (NPY) immunoreactivity has been studied by means of immunocytochemistry and radioimmunoassay in the brain of the goldfish. It was found that NPY had a widespread distribution in the entire brain in particular in the telencephalon, diencephalon, optic tectum and rhombencephalon. In the pituitary gland, positive type-B(More)
The organization of Gn-RH systems in the brain of teleosts has been investigated previously by immunohistochemistry using antibodies against the mammalian decapeptide which differs from the teleostean factor. Here, we report the distribution of immunoreactive Gn-RH in the brain of goldfish using antibodies against synthetic teleost peptide. Immunoreactive(More)
The dopaminergic innervation of the goldfish pituitary gland was studied by immunocytochemistry at the electron-microscope level using highly specific antibodies against dopamine coupled to bovine serum albumin with glutaraldehyde. A satisfactory preservation of the tissue was achieved after immersion in 5% glutaraldehyde in phosphate buffer containing(More)
