Do you remember who won the world series in nineteen sixty- eight, but forget where you left your keys? Are you great at remembering all the details of a story, but lousy when it comes to remembering people’s names? What our brains choose to remember, and exactly how they do it, has been the subject of scientific inquiry1 for quite some time. Several years ago researchers were able to observe some of the changes taking place in the brain as memories form. The technology that allows scientists to do this is a scanning machine called an M. R. I., or magnetic resonance2 imaging machine. This is able to make a real-time, three- dimensional map of certain characteristics of blood flow inside someone’s brain.
