NGRI had less activity especially in the left angular gurus
linked to poor verbal skills
Temporal cortex
No difference between both groups
Occipital cortex
NGRI had more activity
Cerebellum
NGRI had more activity than other groups
Less activity
Reduced glucose metabolism in some areas, notably those linked to violence
Abnormal asymmetries - reduced activity on the left side of the brain greater than the right
Performance of the CPT
Both groups performed similarly in the tasks - any observed differences were not a result of the task performance
Identifiable links between areas of the brain and aggression - provide preliminary evidence that murderers NGRI have different brain function to normal individuals
