Functional magnetic resonance imaging (fMRI)

An imaging technique utilizing the small differences in regional blood flow that accompany the neural activity in the brain associated with performance of a cognitive or motor task as compared to that found during a period of rest (the baseline).  It evaluates cerebral blood flow by looking at the difference between venous oxyhemoglobin and deoxyhemoglobin using the Blood Oxygenation Level Dependent (BOLD) Contrast technique.
