Which function does the hypothalamus control?

The hypothalamus plays a crucial role in regulating a variety of essential physiological processes, and one of its primary functions is the control of hunger. It acts as a central hub for managing appetite and energy balance by interpreting signals related to food intake and energy expenditure. The hypothalamus receives input from various hormones, such as ghrelin, which stimulates appetite, and leptin, which signals satiety. By processing this information, the hypothalamus can trigger responses that drive hunger, influencing behavioral aspects such as the desire to eat.

In contrast to the other functions listed, such as posture, eye movement, and learning, which are managed by different areas of the brain—the cerebellum and brainstem for posture, the occipital lobe for eye movement, and the cerebral cortex for learning—the specific function of appetite regulation distinctly identifies the hypothalamus's role in maintaining homeostasis regarding energy needs. This makes the regulation of hunger the most directly related function under the control of the hypothalamus.
