C) magnetic resonance imaging.
D) a functional MRI.

Question

Quizplus · Accepted Answer

Electrical activity in the brain is captured using an electroencephalogram (EEG) by placing electrodes on the scalp and measuring the underlying electrical activity. Positron emission tomography (PET), magnetic resonance imaging (MRI), and functional MRI (fMRI) all involve different methods of measuring brain activity.
