Question

Quizplus · Accepted Answer

fMRI measures changes in blood flow in the brain using magnetic fields. When an area of the brain is active, it requires more oxygen and glucose, and blood flow increases to supply these nutrients. This increase in blood flow is then detected by the magnetic fields of the fMRI scanner, allowing researchers to identify which regions of the brain are active during different tasks or experiences.
