Quizplus · Accepted Answer

PET (positron emission tomography) scans can detect the presence and movement of radioactive tracers. By tagging a neurotransmitter with a radioactive tracer, PET scans can determine whether there is activity in the area where the neurotransmitter is found, the location of receptors for the neurotransmitter, and the number of receptors for the neurotransmitter. Therefore, all of the above options (A, B, and C) are correct.

If a Neurotransmitter Were to Be Given a Radioactive Tag,a
