Abstract

Structural MRI allows unparalleled in vivo study of the anatomy of the developing human brain. For more than two decades, MRI research has revealed many new aspects of this multifaceted maturation process, significantly augmenting scientific knowledge gathered from postmortem studies. Postnatal brain development is notably protracted and involves considerable changes in cerebral cortical, subcortical, and cerebellar structures, as well as significant architectural changes in white matter fiber tracts (see [12]). Although much work has described isolated features of neuroanatomical development, it remains a critical challenge to characterize the multidimensional nature of brain anatomy, capturing different phases of development among individuals. Capitalizing on key advances in multisite, multimodal MRI, and using cross-validated nonlinear modeling, we demonstrate that developmental brain phase can be assessed with much greater precision than has been possible using other biological measures, accounting for more than 92% of the variance in age. Further, our composite metric of morphology, diffusivity, and signal intensity shows that the average difference in phase among children of the same age is only about 1 year, revealing for the first time a latent phenotype in the human brain for which maturation timing is tightly controlled.

  • Most studies find cortical thickness decreases linearly after age four to five years, although some studies suggest an increase from age six to ten and thinning after ten to twelve.

    “Whereas some studies have suggested that cortical thickness increases from age 6 to 10 years and begins to thin after 10–12 years21,20, most studies find that cortical thickness decreases linearly after age 4–5 years25,27,28.”
  • Association cortices reach peak thickness values later than sensory cortices.

    “Notably, association cortices reach peak thickness values later than sensory cortices (Brown et al., 2012, Raznahan et al., 2011, Sowell et al., 2004).”
  • Only one prior study had used more than one imaging modality to derive an integrated brain development index.

    “Notably, however, only one prior study (Brown et al. 2012) has used more than one imaging modality to derive an integrated index of brain development, which successfully predicted the chronological age of subjects with very high accuracy (subjects aged 3-20, r = 0.96, MAE = 1.03).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
