Figure 9.

Pedigree-based heritability (${\text{h}}_{\text{ped}}^2$) of brain torque profiles estimated using the ABCD and HCP datasets. (A) Bar graphs with error bars illustrate ${\text{h}}_{\text{ped}}^2$ estimates and 95% confidence intervals (CI) for frontal/occipital petalia, bending and shift. (B) Blue lines with error bars represent ${\text{h}}_{\text{ped}}^2$ estimates and 95% CI for sectional width and perimeter asymmetries. Red dots indicate significant heritability (P < 0.05/120). The left hemisphere of the FreeSurfer fsaverage cortical surface template is displayed above the heritability plots as the reference of brain anatomy. (C) Maps of ${\text{h}}_{\text{ped}}^2$ estimates (thresholded at FDR < 0.05/3) and corresponding standard errors (SE) of surface positional asymmetries along the Left-Right (Asym_LR), Antero-Posterior (Asym_AP) and Dorso-Ventral (Asym_DV) axes. $95\%\text{\hspace{0.17em}CI}={\text{h}}_{\text{ped}}^2\pm 1.96\times \text{SE}$.
