ao3 of neural correlates

• What did Milev et al. (2003) study in relation to schizophrenia?

  Decreased grey matter volume in the temporal lobe
• What method did Milev et al. (2003) use to measure temporal lobe tissue volume?

  MRI scans
• What was the sample size of the study conducted by Milev et al. (2003)?

  123 schizophrenics
• What correlation did Milev et al. (2003) find regarding hallucinations?

  Smaller grey matter volume linked to more hallucinations
• What did Ho et al. (2003) research in relation to schizophrenia?

  Enlarged ventricles
• What was the sample size in Ho et al. (2003) study?

  73 schizophrenic patients and 23 controls
• What correlation did Ho et al. (2003) find regarding negative symptoms?

  Negative symptoms increased with ventricle enlargement
• What was the Pearson correlation coefficient found by Ho et al. (2003)?

  $0.44$
• What limitation is associated with research into neural correlates of schizophrenia?

  Difficulty in establishing causality
• Why is it problematic to establish an initial neural cause of schizophrenia?

  Research occurs after diagnosis
• What is a strength of neural correlates as an explanation of schizophrenia?

  Supporting evidence often fulfills scientific criteria
• What imaging techniques are used to study brain features in schizophrenia?

  MRI and PET scans
• What do MRI and PET scans provide in schizophrenia research?

  Objective comparisons between brain types
• What limitation do MRI and PET scans have in schizophrenia research?

  They do not explain why features developed
• What doubt arises from using only scientific methods in schizophrenia research?

  Whether they can provide a full explanation
• What is the significance of the longitudinal nature of Milev et al. (2003) study?

  It allows observation of changes over time
• How do structural and functional abnormalities relate to schizophrenia symptoms?

  They may influence the severity of symptoms
• Why are imaging techniques important in understanding schizophrenia?

  They provide objective data on brain structure
• What is a limitation of correlational studies in schizophrenia research?

  They do not establish causation
