'Brain abnormalities in murders indicated by positron emission tomography'
Aims:
1. 1. To investigate if there were brain differences between violent offenders and normal people
2. 2. To see if people who had committed murder had brain dysfunction in the following areas of the brain: prefrontal cortex, amygdala, hippocampus, thalamus, corpus callosum, and angular gyrus
Procedure:

2. Experimental group: 41 NGRI, 39 males and 2 females. They had different diagnoses which included organic brain damage (23) and schizophrenia (6)
3. Control group: 41 participants matched on age and gender. 39 males and 2 females. They went through a screening process, their medical records were checked, they were checked for general health, physical examination and a psychatric interview. They were excluded if they had experienced head trauma, had a history of seizures or substance abuse.
