median preoptic nucleus
Acronym: MnPO
The term median preoptic nucleus refers to one of five subdivisions of the preoptic area defined on the basis of Nissl stain. It is a predominantly cellular structure located in the human adjacent to the third ventricle, rostral to the anterior commissure. There it is bounded dorsally by the dorsal subdivision of the preoptic periventricular nucleus and ventrally by the paraventricular nucleus of the hypothalamus ( Mai-2004 ); and it is located in the midline dorsal to the organum vasculosum ( Saper-2004 ). In the macaque ( Martin-2000; Paxinos-2009a ), the rat ( Swanson-1998 ) and the mouse ( Hof-2000 ) it is a narrow midline structure that wraps around the dorsal, rostral and ventral surfaces of the decussation of the anterior commissure.
