WebMay 1, 2024 · What is FMRI? Functional magnetic resonance imaging, or FMRI, works by detecting the changes in blood oxygenation and flow that occur in response to neural activity – when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area. FMRI can be used to produce activation … Functional magnetic resonance imaging, or fMRI, is a technique for measuring brain activity.
