Hypothalamus

The hypothalamus is a region of the brain that regulates sleep cycles, body temperature, pituitary gland activity, and other autonomic nervous system functions.

When the hypothalamus malfunctions, thyroid problems, cluster headaches, and sleeping, eating, or reproductive problems may result.
