Quizplus · Accepted Answer

An fMRI measures changes in blood flow within the brain, giving insight into neural activity in specific regions. It does not produce images of structures or provide detailed structural information. It works by detecting and imaging the changes in blood oxygenation levels that occur as a result of increased neural activity in specific brain regions.
