neuroscience

• emergence of cognitive neuroscience

  -study living brain

  -understand info about brain structures involved in different kinds of brain processing

  -position emission tomography

  -functional magnetic resonance imaging

  > see what brain parts are active during certain activities
• study using PET scans- RAINE ET AL (1997)

  -investigated brain activity in 41 murders using PET scans

  -used to assess brain activity by measuring glucose uptake by brain cells

  -more glucose they take up = more active they are

  -reduced glucose metabolism in prefrontal cortex in murderers brains, suggests reduced functioning in PFC in murderers
• study using PET scans - CONCLUSION

  -pre frontal cortex mediates emotional impulses including aggression
• recent advancements in neuroscience

  -computer generated model > developed to 'read' the brain

  -led to mind mapping techniques > 'brain fingerprinting'

  -future use could be analysing brain wave pattern of eye witness to see if lying in court
