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.

Can an unconscious person hear you?

What does our brain do when we sleep?

Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake.

What happens to the brain during unconsciousness?

“We found that during unconsciousness, disrupted connectivity in the brain and greater modularity are creating an environment that is inhospitable to the kind of efficient information transfer that is required for consciousness.”
