What happens to the brain during sleep?

Why do we lose consciousness when we sleep?
Technically sleep starts in the brain areas that produce SWS. Scientists now have concrete evidence that two groups of cells—the ventrolateral preoptic nucleus in the hypothalamus and the parafacial zone in the brain stem—are involved in prompting SWS. When these cells switch on, it triggers a loss of consciousness.

Your body temperature decreases, your eye movements stop, and your heart rate and muscles continue to relax. Your brain waves briefly spike then slow down. During a night of sleep, you spend the most time in stage 2.
What part of the brain shuts down during sleep?
The VLPO promotes sleep by inhibiting activity in the brain’s arousal centers. Another area of the hypothalamus is responsible for shutting down the brain’s arousal signals and causing the transition to sleep.
Can your brain fall asleep?
The phenomenon can occur most readily when a person is sleep-deprived, when their brain is primed to switch into sleep mode at any second. While a person can appear awake and even have their eyes open, their brain may have slipped into sleep mode, maybe reaching the first or second level of sleep. Dr.
What is it called when your eyes stay open but your brain falls asleep?
If you’ve ever been in this awkward situation, you might have experienced “microsleep.” This weird state of consciousness is characterized by brief bursts of sleep that happen while a person is awake — often while their eyes are open and they’re either sitting upright, or even performing a task.
