Impact of Environmental Thermal Stimulation on Activation of Hypothalamic Neuronal Nitric Oxide Synthase during the Prenatal Ontogenesis in Muscovy Ducks

<table>Left: anterior hypothalamus with the preoptic area after Kuenzel and Van Tienhoven [<a href="/journals/tswj/2012/416936/#B46">45</a>], where the investigations were carried out (AC: <i>Commissura anterior</i>, PVN: <i>Nuc. paraventricularis</i>, 3V: third ventricle, AM: <i>Nuc. anterior medialis hypothalami, </i>CO: C<i>hiasma opticum</i>, LHy: lateral hypothalamic area, and FB: forebrain bundle). Right: typical examples of nNOS expression (magnification × 100) in a Muscovy duck embryo on E 23. nNOS positive Neurons were counted in a defined area, which was divided into 100 rectangles of 100 × 100 <i>μ</i>m.</table>
