Localization of Neuropeptide Y-like immunoreactive structures in the brain of the pejerrey, Odontesthes bonariensis (Teleostei, Atheriniformes)
The aim of this study was to determine the distribution of Neuropeptide-Y (NPY) immunoreactive neurons and fibres in the brain and pituitary of Odontesthes bonariensis by immunohistochemical methods. A wide distribution of immunoreactive NPY (ir-NPY) cells and fibres in the forebrain and midbrain wa...
