Quizplus · Accepted Answer

The ventrolateral preoptic nucleus (VLPO) acts like a master switch for sleep, promoting sleep by inhibiting the arousal systems of the brain. It is a key regulator of the sleep-wake cycle and helps to promote slow-wave sleep. It does not play a role in focusing attention, influencing dreams or paralyzing voluntary muscles.
