Functional MRI or functional Magnetic Resonance Imaging (fMRI) is a type of specialized MRI scan and one of the most r ecently developed forms of brain imaging. It is based on the same technology as the MRI -- a noninvasive test that uses a strong magnetic field and radio waves to create detailed images of the body. Even when you rest quietly with your eyes closed the brain is still highly active, and the patterns of activity in this resting state are thought to reveal particular networks of areas that often act together. Functional magnetic resonance imaging (fMRI) is a technique for measuring and mapping brain activity that is noninvasive and safe.
