WebSep 1, 2006 · So according to critics, what fMRI really measures is a correlation between blood flow and activity, and not the brain activity itself. But much of scientific progress starts with seeing some kind of correlation that begs explanation, like Angelo Mosso noticing surges of blood in the unfortunate Bertino’s brain. The data from fMRI provides ... 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.
