functional MRIAbbreviation for functional magnetic resonance imaging.functional MRI Fast MRI Imaging A brain imaging technique that measures ↑ blood flow–BF which, like PET, relies on changes in BF and oxygenation due to brain activity; aerobic metabolism in some neurons creates a local ↑ in deoxyHb, which triggers ↑ BF, maintaining O2 in the immediate vicinity, followed by regional ↑ in BF Neuroscience MRI fitted with special hardware to accelerate imaging speeds and advanced software that turns the static images into movies; FM allows real-time evaluation of cerebral activity as the mind thinks, listens, dreams, and imagines.
