intermediate nucleus of the preoptic area
Acronym: IPA
The term intermediate nucleus of the preoptic area refers to a collection of nerve cells identified by Nissl stain located dorsal and medial to the supraoptic nucleus in the preoptic area of the human and macaque . It is sometimes mistaken for a component of the accessory neurosecretory nuclei. It is judged on the basis of galanin-staining to be the primate equivalent of the ventrolateral preoptic nucleus in the rodent. The nucleus has been related functionally to male sexuality and to sleep regulation ( Saper-2004 ).

Also known as: intermediate nucleus, interstitial nucleus of the anterior hypothalamus 1, sexually dimorphic nucleus, ventrolateral preoptic nucleus, Nucleus intermedius area preopticaNeuroNames ID : 3122
