Anatomical terms of neuroanatomy [edit on Wikidata]

The anterior hypothalamic nucleus is a nucleus of the hypothalamus.

Its function is thermoregulation (cooling) of the body. Damage or destruction of this nucleus causes hyperthermia.

The anterior hypothalamus plays a role in regulating sleep.^[1]

The anterior hypothalamic region is sometimes grouped with the preoptic area.^[2]
