WebFunctional magnetic resonance imaging (fMRI) maps the spatiotemporal distribution of neural activity in the brain under varying cognitive conditions. Since its inception in 1991, blood oxygen level-dependent (BOLD) fMRI has rapidly become a vital methodology in basic and applied neuroscience research. In the clinical realm, it has become an ... WebThe fMRI uses magnetic fields and radio waves to detect these changes in blood flow in the brain. The fMRI can project on the computer which parts of the brain have the increased blood flow, which allows researchers to see …
WebFunctional magnetic resonance imaging (fMRI) operates on the same principles, but it shows changes in brain activity over time by tracking blood flow and oxygen levels. The fMRI provides more detailed images of the brain’s structure, as well as better accuracy in time, than is possible in PET scans (Figure 3). http://fmri.ucsd.edu/Research/whatisfmri.html
