Figure 3. Difference in heritability between vertex-wise shape measures and PCA components.

Plots illustrate the difference between heritability estimates obtained from the vertex-wise shape measures and the heritability of the components obtained through principal component analysis for seven bilateral subcortical structures. Separate panels are provided for the shape measures of radial distance (a,b) and the Jacobian determinant (c,d) and the left (a,c) and right (b,d) hemisphere. All vertex-wise shape measures and principal components were first sorted in descending order of heritablility, and the vertex-wise measures were substracted from the corresponding component's heritability. Colours indicate the different structures (see figure legends).
