eli5: How does getting hit in the jaw result in a knockout?

981 viewsBiologyOther

I like to watch videos of people fighting from time to time and kept seeing videos of people getting put to sleep via jaw shot. How does this work? How does the brain immediately go unconscious like that? What causes the brain to shut off so quickly?

Have a medium sized dog laying under you. Reach down to give that good dog some scritches. Dog senses movement and raises head. Jaw of human has nerves. Skull of dog collide with slacked (open) jaw of human. *clacked* Nerves fire. Human see flash of light and feel confusion. Special spot under jaw has nerves that can feel like you’re chewing Snap Pops from Fourth of July.
