Answer to Question 1

PET scan: Uses an injection of a radioactive substance that, as it decays, produces gamma rays that are detected outside of the head. Greater radioactivity in a particular area indicates greater blood flow to that region.
fMRI: The presence of hemoglobin with oxygen acts differently in a magnetic field than hemoglobin without oxygen. Because active areas of the brain use more oxygen, these areas can be detected by MRI equipment that is sensitive to these magnetic differences.

Answer to Question 2

b
