Brain regions showing significant statistical differences between patients with schizophrenia and patients with bipolar disorder at p = 0.05, corrected for multiple comparisons across space. Panels depict cortical volume (a), cortical thickness (b), cortical surface area (c), and gyrification index (d), respectively. The right side of the image represents the left side of the brain. The statistical maps show uncorrected values (i.e., sig = −log10(p)) masked by the significant clusters. The statistical results were only significant in the direction of reduced values in patients with schizophrenia.
