| Region | Area | Nucleus | Function |
| Anterior | Medial | Preoptic nucleus | Thermoregulation/Heat loss centre |
| Supraoptic nucleus (SO) | vasopressin (ADH) release | ||
| Paraventricular nucleus (PV) | CRHreleaseOxytocinand to a lesser extentantidiuretic hormone | ||
| Anterior hypothalamic nucleus(AH) | Thermoregulation/Heat loss centre (set point comparison) Heat loss if core temp > set point | ||
| Suprachiasmatic nucleus | Circadian rhythms | ||
| Part of supraoptic nucleus (SO) | vasopressin release release | ||
| Tuberal | Medial | Dorsomedial hypothalamic nucleus (DM) | Blood Pressure Heart Rate GIstimulation |
| Ventromedial nucleus (VM) | satiety centre (controls eating)lesion causes voracious appetite | ||
| Arcuate nucleus (AR)/ Infundibular nucleus/ Periventricular nucleus | Endocrine function (releasing hormones) - controls Adenohypophysis | ||
| Lateral | Lateral hypothalamic area | Feeding centre (thirst and hunger)- lesion causes anorexia | |
| Posterior | Medial | Mammillary nuclei (part of mammillary bodies) (MB) | memory feeding reflex |
| Posterior nucleus (PN) | Increase blood pressure Pupillary dilation Thermoregulation (generates shivering, if core temp <set point) |
