Cross-sectional studies have found functional connectivity differences in the brain's default mode network in aging, mild cognitive …
May 1, 2022 · 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 maps showing which ... fMRI is based on the same technology as magnetic resonance imaging ( MRI) -- a noninvasive test that uses a strong magnetic field and radio waves to create detailed images of the body. But instead of creating images of organs and tissues like MRI, fMRI looks at blood flow in the brain to detect areas of activity.Keck School of Medicine of USC researchers, working with a Caltech team, demonstrate possibilities of innovative imaging technology to visualize brain function.
