right hemisphere, coinciding with previous studies showing these regions to develop late into adolescence (Giedd 2004; Gogtay et al. 2004; Sowell et al. 2002a, b). Examination of developmental changes in cortical thickness from 8–30 years of age indicates a similar pattern of nonlinear declines, with marked thinning during adolescence. Attenuations are most notable in the parietal lobe, and followed in effect size by medial and superior frontal regions, the cingulum, and occipital lobe (Tamnes et al. 2009).
