Findings

• What technology was used in the study of brain abnormalities in murderers?

  Position emotion technology
• What was found regarding brain activity in NGRI participants?

  Reduced activity in violence-linked brain areas
• Which brain areas showed reduced activity in NGRI participants?

  Prefrontal cortex, left angular gyrus
• In which hemisphere was reduced activity observed in the amygdala?

  Left hemisphere
• Which brain areas showed increased activity in NGRI participants?

  Cerebellum, right hemisphere
• What was the finding regarding glucose metabolism in murderers?

  Reduced glucose metabolism in violence-linked areas
• How did the performance on the CPT compare between the NGRI group and the control group?

  Both groups performed similarly on the CPT
• What factors did not show significant differences in the study?

  Ethnicity and head injury
• What is the significance of the findings related to the NGRI participants?

  Indicates brain abnormalities linked to violence
• What can be inferred about the relationship between brain activity and violent behavior from the study?

  Reduced activity in certain areas may relate to violence
• Why can't the differences in brain activity be linked to performance on the CPT?

  Both groups performed similarly on the task
• Which areas showed no differences between NGRI and control groups?

  Caudate, putamen, globus pallidus, midbrain
• What does NGRI stand for in the context of the study?

  Not Guilty by Reason of Insanity
• How does the study contribute to understanding violent behavior?

  Links brain abnormalities to violent tendencies
