ELI5: How does knocking a person out work?

Something I've always wondered.  A good strong punch, a pistol whip to the back of the head, karate chops...  How is it all supposed to work physiologically?

Not a doctor, not a scientist, but it's an overload. When trauma occurs to the brain like that, certain things happen. All of your senses more or less are stimulated by the impact to the tissue of the brain. It's like when you get hit in the nose ans see white for a second, when you get dizzy from spinning around...imagine all of these happening at once. it's a protective measure of your brain to "shut off," a bit like tripping a breaker, but it can reset itself.
