Functional magnetic resonance imaging - Wikipedia

WebFunctional Magnetic Resonance Imaging (fMRI) FMRI is a method of measuring the flow of oxygenated blood in the brain (Ogawa et al., 1990A, 1990B; Bandettini, 1992). FMRI is based on the BOLD effect where BOLD stands for blood oxygen-level dependent. 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 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]
