Study Sheds Light on Development and Evolution of the Human Hypothalamus

The hypothalamus is a small but critical region at the base of the brain that controls the autonomic nervous system, regulates body temperature, signals hunger and thirst, exerts hormonal control over the pituitary gland, helps set circadian rhythms, influences sexual behavior and reproduction, and plays a role in instinctive behaviors like fear, aggression, and maternal bonding.
