Summary
Functional magnetic resonance imaging or functional MRI (fMRI) is a functional neuroimaging procedure usingMRI technology that measures brain activity by detecting changes associated with blood flow.
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.
