Orlando Serrell from Virginia was 10 when he was struck by a baseball on his temple during a game. He lost consciousness for a while, but when he woke up again, everything seemed to be normal.

Where does memory come from? Why do we remember some things and forget others? What kind of filters are responsible for recording some data and deleting others? Or do we record every
