Changes in heritability of cortical thickness during childhood and adolescence (adapted from Lenroot et al, 2009)
[Heritability (a2) at ages 5, 12 and 18 years for superior, inferior, right and left cortical surfaces. Values at each age were derived from the modeled interaction of age as a continuous variable with estimates of genetic and environmental variance components. Colorbar shows scale of heritability values from 0.0 to 1.0 [color version available in online article: doi: 10.1111/j.1469-7610.2011.02381.x]]
