Brain regions with significant genetic effects on cortical thickness (a) and its hemispheric asymmetry (b). Each vertex is color-mapped for level of significance following the application of an FDR threshold. Since there is no region with a significant genetic effect in the right hemisphere, only the left hemispheric cortical surface is displayed. In particular, Broca’s area (BA 44), parahippocampal gyri (BA 34) and the medial region of primary somatosensory cortex (BA 1, 2, 3) showed a statistically significant heritability of cortical thickness (a). These areas were included in regions of significantly heritable hemispheric asymmetry (b). It meant that left-lateralized genetic influences on cortical thickness were rather caused by structural asymmetry.
