- practice CPT beforehand
- injected with tracer 30s after starting CPT
- 32m after injection, PET scan to record 10 horizontal slices of brain
3
Q
FINDINGS
A
- abnormal asymmetries
- reduced activity in areas linked to violence e.g. prefrontal cortex, left hemi hippocampus
- increased activity in areas not linked e.g. cerebellum. right hemi amygdala
- no difference between NGRI and control group e.g. putamen and midbrain
