- Neural correlates
- Outline (A01)
- Both positive and negative symptoms originate in the brain
- Research methods; post-mortems and f-MRI scans
- f-MRI scans allow localisation
- Schizophrenics have abnormally large ventricles, causing damage to central brain areas and pre-frontal cortex
- Damage associated with negative symptoms
- Research evidence
- Boos et al (2012) Schizophrenics had less grey matter than control
- Suggests brain tissue
- Tilo et al (2001) Severity of thought disorder negatively correlated with activity in Wernicke's area (area for coherent speech)
- Shows localisation
- Boos et al (2012) Schizophrenics had less grey matter than control
- Evaluate (A03)
- Enlarged ventricles don't automatically mean schizophrenia
- Ecplains why some patients don't respond well to medication
- Too reductionist; ignores social characteristic
- Lewis (1990) No major link between enlarged ventricles and negative symptoms
- Empitical methods (scientific)
- Outline (A01)
