The strangest brains that ever lived. There's a man who memorized over 12,000 books, word for word. Ask him the day of the week for any date in history, and he'd answer instantly. And yet, he couldn't button his own shirt. His name was Kim Peek. When he was born in 1951, doctors looked at his unusually large head, assumed severe brain damage, and told his parents to put him in an institution and move on with their lives. They were wrong about almost everything except one detail. Kim's brain really was different. He'd been born missing the corpus callosum — the thick bridge of nerve fibers that normally lets the left and right halves of the brain talk to each other. His two hemispheres were essentially operating alone.
