The posterior nucleus of the hypothalamus is one of the many nuclei that make up the hypothalamic region of the brain.

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

v • d • e Brain: diencephalon

Epithalamus	Pineal body • Habenula (Habenular nuclei) • Stria medullaris • Habenular trigone • Habenular commissure

Thalamus/nuclei	paired: AN • Ventral (VA/VL, VP/VPM/VPL) • Lateral (Pulvinar) • Metathalamus (MG, LG) midline: MD • Intralaminar (Centromedian) • Midline nuclear group • Interthalamic adhesion • Medullary laminae surface: reticular tracts to thalamus: Mammillothalamic tract • Thalamic fasciculus • Lenticular fasciculus • Ansa lenticularis • Medial lemniscus • Trigeminal lemniscus • Spinothalamic tract • Lateral lemniscus

Hypothalamus	autonomic zones: Anterior (parasympathetic/heat loss) • Posterior (sympathetic/heat conservation) endocrine - posterior pituitary: magnocellular/Paraventricular/Supraoptic (oxytocin/vasopressin) endocrine - other: parvocellular/Arcuate (dopamine/GHRH) • Preoptic (GnRH) • Suprachiasmatic (melatonin) emotion: Lateral (hunger) • Ventromedial (satiety) • Dorsomedial (rage) surface: Median eminence/Tuber cinereum • Mammillary body • Infundibulum tracts: Medial forebrain bundle Pituitary: (Posterior is diencephalon, but anterior is glandular)

Subthalamus	Subthalamic nucleus • Zona incerta
