Comparison of visual ROI cortical thickness by group and region. Across groups, retinotopic cortex was significantly thinner than LOC. Across ROIs, cortical thickness was significantly different between the participant groups: schizophrenia patients had the thinnest cortex in both ROIs, followed by bipolar patients, and healthy controls had the thickest cortex in both areas. In a direct comparison, schizophrenia patients had significantly thinner cortex than healthy controls across both ROIs, but comparisons between bipolar patients and the other two groups showed only trend-level differences. No significant group-by-ROI interaction was present in the data.
