Question

Quizplus · Accepted Answer

An electroencephalograph (EEG) is a device used to record the electrical activity in the brain. This is done by placing electrodes on the scalp to measure the electrical signals coming from the brain. The other options, such as computerized axial tomography (CAT) scans, functional magnetic resonance imaging (fMRI), and positron emission tomography (PET) all provide different types of brain imaging, but do not directly record electrical activity.
