An fMRI scan can show a lot. But since the technique does not image neurons directly, it cannot reveal how the parts of the brain’s language system signal each other. It can’t outline the routes of the signals or the order in which they travel. “The technologies that we really want as brain scientists don’t exist yet,” says Marcus.Medically Reviewed Functional magnetic resonance imaging, or fMRI, is a special type of magnetic resonance imaging ( MRI) that measures brain activity by detecting changes in blood flow.

By using the blood’s magnetic ...
Functional magnetic resonance imaging or functional MRI ( fMRI) measures brain activity by detecting changes associated with blood flow. [1] [2] This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. [3]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 ... …
