title: [Presence of neurons synthesizing LH-RH in the anterior hypothalamus of the duck (Anas platyrhynchos)].
abstract: Using histochemical techniques with LH-RH anti-serum, a large number of LH-RH producing neurons were identified in the Duck hypothalamus, under different physiological conditions. The LH-RH pericaryas were localized in a well delimited area of the anterior hypothalamus, including the dorsal part of the periventricular preoptic nucleus. The LH-RH containing axons were directed downwards towards the infundibulum, and terminated within the external layer of the rostral and caudal median eminence, in close vicinity to the capillaries of the pituitary portal system.
