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.
