説明
<jats:title>Significance</jats:title> <jats:p> Our spatiotemporal understanding of subcortical development in humans lags far behind that of the cortical sheet. This disparity ignores that developmental refinements and disruptions of complex behavior involve systems spanning both components of the brain. We begin redressing this imbalance by applying new techniques for striatal, pallidal and thalamic morphometry to large-scale longitudinal neuroimaging data extending from childhood through early adulthood. This work ( <jats:italic>i</jats:italic> ) establishes the curvilinear, sexual dimorphic and often protracted nature of global volume change within each structure, ( <jats:italic>ii</jats:italic> ) reveals profound spatiotemporal complexities in striatal, pallidal and thalamic maturation that are organized by the known topography of primate cortico-subcortical connectivity, and ( <jats:italic>iii</jats:italic> ) identifies focal sex differences in subcortical maturation that strike regions implicated in psychopathologies with an adolescent-emergent sex-bias. </jats:p>
