Estimates of heritability in subcortical shape. Varying extents of the bilateral accumbens (a), amygdala (b), caudate (d), putamen (f) and thalamus (g), and portions of left hippocampus (c) and left pallidum (e) were found to be significantly heritable. Many of these subfields have high heritability estimates (h2 >0.8). Notably, subcortical volumes that were not heritable (e.g. amygdala) do have focal subfields that are heritable based on shape analysis. Maps show are FDR corrected thresholded at p<.05
