Quizplus · Accepted Answer

The hypothalamus is responsible for controlling the sleep-wake cycles, as well as regulating various other important processes in the body, such as hunger and body temperature. The pineal gland is also involved in regulating sleep-wake cycles, as it secretes the hormone melatonin during periods of darkness, which helps to promote sleepiness. The medulla oblongata, thalamus, and visual cortex all have other important functions, but are not directly involved in regulating sleep-wake cycles.
