Question

Quizplus · Accepted Answer

Functional MRI (fMRI) measures changes in blood flow to different areas of the brain. When certain areas of the brain become more active, they require more oxygen and nutrients, which is supplied by an increase in blood flow carrying oxygenated blood. Therefore, fMRI generates images of increases in oxygenated blood flow.
