Quizplus · Accepted Answer

An amplified recording of the waves of electrical activity that sweep across the surface of the brain is called an EEG (electroencephalogram). fMRI (functional magnetic resonance imaging) measures changes in blood flow, PET scan (positron emission tomography) measures metabolic activity, and MRI (magnetic resonance imaging) produces detailed images of the brain's structure.
