Question

Quizplus · Accepted Answer

The hypothalamus is responsible for regulating the sleep-wake cycle through the release of hormones and activation of various neural pathways. It is often referred to as the "master clock" of the body. The optical nerve and frontal lobe play important roles in vision and cognitive processing, respectively, but do not have direct control over the sleep-wake cycle. The median forebrain bundle is a pathway involved in reward and motivation, and is not directly related to sleep regulation.
