<P> Functional magnetic resonance imaging or functional MRI ( fMRI ) 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 . </P>
