Biological basis of behavior
Biological Basis of
Behavior
So our brain chemistry is
responsible for our
behavior?
CT scans
CT scans can give detailed images
of many types of tissue, including
bone, lung tissue, soft tissue and
blood vessels.
Use with caution because of
radiation
Ways to study the brain
CT Scans
CT scans
• can be used to check for
suspected brain tumours
and bleeding or swelling of the
arteries;
• useful for investigating the
brain following a stroke (when
the blood supply to part of the
brain is cut off)
MRI Scans
- radio waves are used to create
brain images
MRI
Advantages of an MRI
• They give a view of the brian without using
harmful x-rays
Pet Scans
- Injecting radiation into the
bloodstream to identify where the
activity is In the brain
PET Scan of the Brain
PET MRI or CT?
• Non harmful radio waves are used
• Radiation is injected into the
blood stream
• Used to see structures of the
brain
• Use with caution
• Used to see brain activity
