WebThe idea underpinning functional magnetic resonance imaging (fMRI) is to infer brain activity by assessing changes in brain circulation. Increased brain activity accompanies significantly elevated cerebral blood flow (CBF). Italian physiologist Angelo Mosso first observed the phenomenon in the late nineteenth century. WebFMRI 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 …
