Quizplus · Accepted Answer

fMRI (functional magnetic resonance imaging) specifically detects brain activity by measuring changes in blood oxygenation that occur in response to neural activity. This allows researchers to map out which areas of the brain are involved in various cognitive processes or tasks. The other imaging techniques listed (MRI, EEG, PET scan, and CAT scan) may provide valuable information about brain structure or function, but they do not specifically measure blood flow as an indicator of activity.
