Hypothalamus:
- Lateral nucleus: activates hunger/thirst.
- Medial preoptic nucleus: releases GnRH.
- Anterior nucleus: regulates temperature.
- Supraoptic and paraventricular nuclei: produces ADH & oxytocin.
- Suprachiasmatic nucleus: circadian pacemaker.
- Ventromedial nucleus: satiety center.
- Dorsomedial nucleus: activates aggression.
- Posterior nucleus: heat conservation.
- Mamillary bodies: Memory formation.
