Verified step by step guidance

1. Understand that the brain has different regions responsible for various functions, including regulating sleep.
2. Recall that the cerebellum is mainly involved in motor control and coordination, not sleep regulation.
3. Recognize that the occipital lobe primarily processes visual information, so it is not responsible for sleep.
4. Know that the amygdala is involved in emotions and memory, but it does not regulate sleep.
5. Identify the hypothalamus as the brain region that contains the suprachiasmatic nucleus, which controls circadian rhythms and regulates sleep-wake cycles.
