The suprachiasmatic nuclei is responsible for regulating the circadian rhythm, which controls the sleep-wake cycle. Bert's tendency to wake up early and get tired early in the evening suggests he has an earlier natural clock, while Ernie's preference for staying up late and sleeping in suggests he has a later clock. The thalamus and amygdala are not directly involved in regulating sleep, and the corpus callosum is a structure involved in connecting the two hemispheres of the brain.
