Question

Quizplus · Accepted Answer

An EEG (electroencephalogram) measures electrical activity in the brain and is often used to study brain wave patterns associated with different psychological and physiological disorders. CT scans and MRI scans are useful for visualizing the structure of the brain, but do not measure electrical activity. PET scans (positron emission tomography) can detect changes in blood flow and metabolism in the brain, but are not as useful as EEG for examining brain wave patterns.
