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

1.36K 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?

When your head is hit from the side (jaw or temple) the two halves of your brain momentarily lose connection. It’s like unplugging your desktop computer. Yes, you can restart it. But the action of juggling your left and right side of your brain so they move in opposite directions “shorts out” your brain. You don’t have to hit someone hard to knock them out. You have to hit them right.
