Which of the following is NOT a function of the hypothalamus?

The hypothalamus plays a crucial role in several vital functions related to homeostasis and physiological regulation in the body. It is well-known for its involvement in controlling hunger, regulating body weight, and managing the body's chemical balance through hormonal secretion and autonomic functions.

Controlling hunger involves the hypothalamus integrating signals related to energy intake and expenditure, thus influencing appetite and eating behavior. Regulating body weight is closely linked to this function, as the hypothalamus communicates with various neurotransmitters and hormones that signal satiety and hunger. Additionally, the hypothalamus is responsible for managing the body’s chemical balance by regulating the release of hormones from the pituitary gland, thus influencing processes like thirst, temperature regulation, and metabolism.

In contrast, short-term memory, while an important cognitive function, is primarily associated with the hippocampus and other areas of the brain that are more directly involved in memory processing. Therefore, controlling short-term memory does not fall within the primary functions of the hypothalamus, making it the correct answer to the question.
