Neural correlates

• Brain structure or function

  > Enlarged ventricles

  > A meta-analysis by Raz and Raz found that over half of individuals tested, with schizophrenia had increased ventricle size compared to a control group

  > Enlarged ventricles are associated with damage to central brain areas and the pre-frontal cortex, damage is associated with negative symptoms of schizophrenia
• Neural correlates AO3

  :) RTS Suddath et al

  > He used MRI scans to investigate the brain structure of MZ twins in which one twin was schizophrenic

  > They found the schizophrenic twin generally had more enlarged ventricles

  > This suggests enlarged ventricles do play a role in determining the likelihood of schizophrenia developing
