I'm flat on my back in a very loud machine, trying to keep my mind quiet. It's not easy. The inside of an fMRI scanner is narrow and dark, with only a sliver of the world visible in a tilted mirror above my eyes. Despite a set of earplugs, I'm bathed in a dull roar punctuated by a racket like a dryer full of sneakers.

Functional magnetic resonance imaging - fMRI for short - enables researchers to create maps of the brain's networks in action as they process thoughts, sensations, memories, and motor commands. Since its debut in experimental medicine 10 years ago, functional imaging has opened a window onto the cognitive operations behind such complex and subtle behavior as feeling transported by a piece of music or recognizing the face of a loved one in a crowd.

As it migrates into clinical practice, fMRI is making it possible for neurologists to detect early signs of Alzheimer's disease and other disorders, evaluate drug treatments, and pinpoint tissue housing critical abilities like speech before venturing into a patient's brain with a scalpel.
