Which part of the brain is responsible for regulating body temperature?

The hypothalamus plays a crucial role in regulating body temperature, often referred to as thermoregulation. It acts as a thermostat for the body, receiving input from temperature receptors in the skin and other parts of the body. When it detects changes in temperature, the hypothalamus initiates physiological responses to either conserve heat or increase heat loss, helping to maintain a stable internal body temperature.

In contrast, the cerebellum is primarily involved in motor control and coordination, the thalamus serves as a relay center for sensory information, and the cerebrum is responsible for higher cognitive functions such as thinking, memory, and emotion. None of these areas are primarily responsible for temperature regulation, making the hypothalamus the clear choice for this function.
