Genesis Jackson · Accepted Answer

Final Answer : C, Explanation :  The hypothalamus is responsible for regulating various physiological processes including the sleep-wake cycle. It receives input from the retina and helps to synchronize the sleep-wake cycle with the light-dark cycle. Other structures such as the pineal gland and the suprachiasmatic nucleus (SCN) also play a role in regulating the sleep-wake cycle, but the hypothalamus is the ultimate controller. The other options (A, B, and D) are not directly involved in regulating the sleep-wake cycle.

The sleep-wake cycle is ultimately controlled by the part of the brain called the ________.
