Quizplus · Accepted Answer

PET (Positron Emission Tomography) scan is the most useful technology to determine brain activity as it measures glucose metabolism in different parts of the brain. As the brain becomes more active, the glucose consumption also increases, which can be detected by the PET scan. Therefore, the researchers can use a PET scan to locate which area of the rat's brain is more active as it listens to music.
