Functional magnetic resonance imaging (fMRI), which measures changes in blood flow throughout the brain, has been used over the past couple of decades for a variety of applications, including “functional anatomy”—a way of determining which brain areas are switched on when a person carries out a particular task. fMRI has been used to look at people’s brains while they’re doing all sorts of things—working out math problems, learning foreign languages, playing chess, improvising on the piano, doing crossword puzzles, and even watching TV shows like “Curb Your Enthusiasm.”
