Hypothesis
What is the relationship between exploratory eye movement and brain morphology in schizophrenia?
Conclusion
Schizophrenic patients showed lower responsive search scores and widespread gray matter loss in specific brain areas associated with visual processing and eye movement control.
Supporting Evidence
- Schizophrenic patients had significantly lower responsive search scores compared to healthy controls.
- Gray matter density reductions were observed in several brain regions associated with visual processing.
- RSS was positively correlated with gray matter density in specific brain areas in schizophrenic patients.
Takeaway
People with schizophrenia have trouble moving their eyes in a normal way, and this is linked to changes in their brain structure.
Methodology
The study involved 33 schizophrenic patients and 29 healthy controls who underwent exploratory eye movement tasks and MRI scans to analyze brain structure.
Potential Biases
Potential bias due to the exclusion of patients with certain conditions and the reliance on self-reported data.
Limitations
The study's findings may be influenced by the patients' exposure to antipsychotic medication and the lack of cognitive function measures.
Participant Demographics
33 schizophrenic patients (19 male, 14 female) and 29 healthy controls (17 male, 12 female), matched for age and education.
