Question

Quizplus · Accepted Answer

An EEG (electroencephalogram) assesses brain function by measuring electrical impulses by way of electrodes placed on parts of the scalp. MRIs (magnetic resonance imaging), CAT scans (computerized axial tomography), PET scans (positron emission tomography), and PAT scans (positron axial tomography) are all types of brain imaging procedures that use different techniques to visualize the brain, but do not directly measure electrical activity in the brain.
