Fmri works because:
WebDefinition. 1 / 12. fMRI works by detecting the changes in blood oxygenation and flow that occur as a result of neural (brain) activity in specific parts of the brain. A more active brain area consumes more oxygen, thus meaning it has a higher demand for oxygen. To meet this increased demand blood flow is directed to the active area (known as ... WebBecause the changing distribution of oxygenated blood in the brain is known to correlate with neural activity, fMRI can be used to image the parts of a patient’s brain that become …
