Functional magnetic resonance imaging (fMRI) is used to visualize brain function, by visualizing changes in chemical composition of brain areas or changes in the flow of fluids that occur over timespans of seconds to minutes.
BOLD (Blood Oxygenation Level Dependent) fMRI operates on the principle that hemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. The contrast between oxygenated and deoxygenated hemoglobin can be used as an indicator of cerebral blood flow to areas with increased neural activity.
