Human Brain Development: a cross-sectional and longitudinal study integrating multiple neuromorphological features

Abstract: Brain maturation studies typically examine relationships linking a single morphometric feature with aspects of cognition, behavior, age, or other demographic characteristics. However, the coordinated spatiotemporal arrangement of morphological features across development and their associations with behavior are unclear. Here, we examine covariation across multiple cortical features (cortical thickness [CT], surface area [SA], local gyrification index [GI], and mean curvature [MC]) using magnetic resonance imag… Show more

“…Demographic, neuroimaging, developmental, and lifestyle factors are known sources of nonage-related variability ( 10 13 ). MAEs in predicting individualized change were significantly higher in males relative to females and across all models examined for GMV and SA but not for CTh and FA ( SI Appendix , Fig.…”

“…Another major challenge presented by cross-sectional normative models is distinguishing age-related variability from nonage-related determinants of change. Different constellations of characteristics attributable to individuals, such as neuroimaging confounds, interscan interval, and lifestyle factors are known sources of nonage-related variability ( 10 13 ). Such variability may explain why person-specific rates of change in common MRI measures (e.g., cortical volume and thickness) ascertained directly from longitudinal measurements can often depart from group-level age-related brain trends—e.g., upward instead of downward slopes in gray matter volume (GMV) with advancing age ( 14 ).…”
