The hypothalamus is the most inferior portion of the diencephalons and contains several small nuclei and nerve tracts. The hypothalamus is very important in a number of functions, all of which have emotional and mood relationships:
| Function | Description |
| Autonomic | Helps control heart rate, urine release from the bladder, movement of food through the digestive tract. |
| Endocrine | Helps regulate pituitary gland secretions and influences metabolism, ion balance, and sexual development. |
| Muscle control | Controls muscles involved in swallowing and stimulates shivering in several muscles. |
| Temperature regulation | Promotes heat loss when the hypothalamic temperature increases by increasing sweat production and promotes heat production when the hypothalamic temperature decreases by promoting shivering. |
| Regulation of food and water intake | Hunger center promotes eating and satiety center inhibits eating; thirst center promotes water intake. |
| Emotions | Large range of emotional influences over body functions; directly involved in stress-related and psychosomatic illnesses and with feelings of fear and rage. |
| Regulation of the sleep-wake cycle | Coordinates responses to the sleep-wake cycle with other areas of the brain. |
