What does functional magnetic resonance imaging (fMRI) measure?

Question

Quizplus · Accepted Answer

fMRI measures changes in blood oxygen levels, which are associated with neural activity in the brain. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When a brain area is more active, it consumes more oxygen, and to meet this demand, blood flow to the area increases. The fMRI detects these changes in blood oxygenation and flow, allowing researchers to infer brain activity.
