A short YouTube video (Rich Bello, Feb 5, 2024) explaining a physiological mechanism behind sleep: the thalamus acts as a gating mechanism that progressively closes when you fall asleep, blocking external sensory signals from reaching the cerebral cortex so they are not consciously perceived, which produces loss of awareness.

Chapters

What actually is happening when you're asleep. There's a gating mechanism that goes on the thalamus. And basically that gating mechanism opens and closes. So it closes when you fall asleep. That's what it's doing is closing, closing, closing, closing, closing. And then it blocks these outside senses from coming in and getting to your cerebral cortex where they're consciously perceived. Now, these senses are not getting to your cerebral cortex. All kinds of noises, all these things can be happening, but doesn't get to your cerebral cortex. You're not perceiving anything. You are asleep, causes us to lose awareness.
