detect & treat violent behaviour

• what does research evidence criminal behaviour is caused by?

  biology
• who is an example of neuroscience predicting violent behaviour?

  Raine et al
• what did Raine et al use?

  PET scans
• what did Raine et al use PET scans for?

  to measure brain difference in NGRI murderers & non-murderers
• what did Raine et al find?

  differences in activity of cortical & sub cortical regions of murderers & non-murderers brains
• what difference was in the limbic system?

  reduced in left hemipshere, increased in right hemisphere of murderers brains
• what makes up the limbic system

  amygdala, hippocampus & thalamus - linked to violent behaviour
• who conducted further research?

  Raine
• what was Raines further research?

  use of PET scans on committed murderers
• what did Raines further research show?

  poot functioning in prefrontal cortex - related to mood control & impulse control
• what has been identified due to studies?

  both studies identified link between brain & violent behaviour
• therefore...

  the ethical benefit of this research is that neuroscience may be able to predict criminal behaviour and prevent it
