WebOct 1, 2008 · fMRI is based on the idea that blood carrying oxygen from the lungs behaves differently in a magnetic field than blood that has already released its oxygen to the cells. In other words, oxygen-rich blood and oxygen-poor blood have a different magnetic resonance. Scientists know that more active areas of the brain receive more oxygenated blood. list of staffordshire railway stations
