What was the main focus of Raine's (1997) research using PET scans?

• A. To analyze brain differences related to nutrition and health
• B. To investigate brain differences in individuals charged with murder
• C. To evaluate brain response to emotional stimuli
• D. To explore learning patterns in aggressive children

Answer: (B)

Raine's research in 1997 primarily aimed to investigate brain differences in individuals charged with murder, specifically examining the neurological underpinnings of violent behavior. Utilizing PET scans, he focused on identifying anomalies in brain activity, particularly in areas associated with impulse control, aggression, and decision-making, such as the prefrontal cortex and the amygdala. This line of inquiry seeks to understand the biological factors that may contribute to violent crime, highlighting the complex interplay between biological predispositions and behavior. By concentrating on individuals who engaged in such extreme actions, Raine aimed to provide insights into the potential cerebral correlates of criminal behavior and how brain functions can influence aggressive tendencies.
