- (D) PET scans provide information about which parts of the brain are most active, which would
reveal that all parts of the brain are used (although different areas of the cerebral cortex are more
active than others on different tasks). CAT and MRI scans only provide information on the structure
of the brain, not brain activity. An EEG scan does provide information about brain wave activity,
but does not tie this activity to specific areas of the brain. And EKG is a scan of heart function, not
related to brain activity.
