Paraventricular nucleus of hypothalamus - Wikipedia
The paraventricular nucleus of hypothalamus (PVN, PVA, or PVH) is a nucleus in the hypothalamus, that lies next to the third ventricle. Many of its neurons project to the posterior pituitary where they secrete oxytocin, and a smaller amount of vasopressin.
