D)functional magnetic resonance imaging (fMRI)

Question

Quizplus · Accepted Answer

Positron emission tomography (PET) is the brain-imaging method described in the question. It involves injecting a radioactive dye that attaches to glucose in the brain, and then using a computer to create a color-coded image of the brain's activity. EEG measures electrical activity in the brain, CT and MRI offer detailed images of the brain's structure, and fMRI measures changes in blood flow to identify brain activity.
