Web9 jun. 2024 · Functional magnetic resonance imaging (fMRI) is a brain-scanning technique that measures blood flow in the brain when a person performs a task. fMRI works on the premise that neurons in the brain that are the most active (during a task) use the most energy. An fMRI creates a dynamic (moving) 3D map of the brain, highlighting which … Functional magnetic resonance imaging, or fMRI, is a technique for measuring brain activity. It 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 … Meer weergeven The development of FMRI in the 1990s, generally credited to Seiji Ogawa and Ken Kwong, is the latest in long line of innovations, … Meer weergeven The attractions of FMRI have made it a popular tool for imaging normal brain function especially for psychologists.
