What advantages do Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET scan) offer in studying the brain?
What will be an ideal response?
ANSWER:
?The MRI uses a magnetic field to create a computer-generated image of the brain. This allows physicians and psychologists to study the brain’s structure in great detail. The PET scan uses radioactive glucose to gauge which areas are most active. The PET scan allows psychologists and physicians to see how the brain is working by showing which areas consume the most radioactive glucose.
