Center for functional magnetic resonance imaging

What is fMRI? fMRI stands for "functional magnetic resonance imaging" and is a technique used by scientists and medical professionals to map activity in the brain. When our brains are active, such as when we talk or complete a math problem, the parts of the brain that are being used require more energy in the form of glucose.
