A drawback of PET scans compared to newer techniques, such as magnetoencephalography, is that:
a. PET is slower, which means it is more difficult to measure moment-to-moment changes in brain activity.
b. PET is faster, which makes it difficult to figure out how brain activity relates to what someone sees or hears.
c. PET is too expensive for practical use.
d. PET is slower, and it does not provide a picture of the brain.
Answer: A
Rationale: Glucose uptake in the brain is a relatively slow process, so there is a long delay between the presentation of a stimulus and a brain response that the PET scan can detect.
