Genetic Associations with Neuroimaging Anatomic Variability

Gutman et al. recently published an interesting paper about the role of genetics in explaining surface variability in neuroimaging-defined structures. It’s common to consider the role of heritability in explaining facial structure — such as nose shape — but, perhaps since the brain is not so easily seen, it’s less common to imagine that heritability could explain variability in brain structures. And it raises the question, could this help explain variability in susceptibility to diseases such as Alzheimer’s as well?
