WebFunctional 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 … WebfMRI is a non-invasive diagnostic test that provides an indirect measure of blood flow to nerve cells. When an area of the brain is in use, blood flow to that region also increases, when a brain area is less active blood flow decreases. Functional MRI was developed in the 1990s and has been used as a valuable research tool. sigil free download
