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;brain tumours useful for investigating the brain following a stroke (when the blood supply to part of the brain is cut off)stroke

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
