Quizplus · Accepted Answer

Positron emission tomography (PET) is a brain-imaging method in which a small amount of radioactive sugar is injected into the subject and a computer compiles a color-coded image of the activity of the brain. This allows researchers to see which areas of the brain are most active during certain tasks or under certain conditions.
