Abstract

The human brain is organized into a collection of interacting networks with specialized functions to support various cognitive functions. Recent research has reached a consensus that the brain manifests small-world topology, which implicates both global and local efficiency at minimal wiring costs, and also modular organization, which indicates functional segregation and specialization. However, the important questions of how and when the small-world topology and modular organization come into existence remain largely unanswered. Taking a graph theoretic approach, we attempt to shed light on this matter by an in vivo study, using diffusion tensor imaging based fiber tractography, on 39 healthy pediatric subjects with longitudinal data collected at average ages of 2 weeks, 1 year, and 2 years. Our results indicate that the small-world architecture exists at birth with efficiency that increases in later stages of development. In addition, we found that the networks are broad scale in nature, signifying the existence of pivotal connection hubs and resilience of the brain network to random and targeted attacks. We also observed, with development, that the brain network seems to evolve progressively from a local, predominantly proximity based, connectivity pattern to a more distributed, predominantly functional based, connectivity pattern. These observations suggest that the brain in the early years of life has relatively efficient systems that may solve similar information processing problems, but in divergent ways.

  • The centrality of the pre-cuneus and cuneus still increases before pre-adolescence.

    “The centrality of the pre-cuneus and cuneus still increases before pre-adolescence (Huang et al., 2015; Yap et al., 2011).”

    From Quantitative mapping of the brain’s structural connectivity using diffusion MRI tractography: A review (2022) · cites this paper as Yap et al., 2011

    The Results section on pediatric network organization reports high centrality for the precuneus and changes in nodal roles across the first two years of life (Fig. 9; no page given). It does not establish that centrality increases for either the precuneus or cuneus, or that such an increase continues up to pre-adolescence. (LLM, conf=0.83)

  • Neonatal brains already show a structural hub distribution similar to adult brains.

    “although neonatal brains already show similar structural hub distribution as adult brains”

    From Quantitative mapping of the brain’s structural connectivity using diffusion MRI tractography: A review (2022) · cites this paper as Yap et al., 2011

    The Results sections on broad-scale networks and nodal roles report connection hubs in the neonatal network, but they do not compare the neonatal hub distribution with that of adults. The nodal-roles Results instead report substantial changes over the first two years; the Discussion’s reference to adult-like patterns concerns two-year-olds, not neonates. No page numbers were provided in our copy. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Many refinements occur for the topological roles of each node after the neonatal period.

    “many refinements occur for the topological roles for each node (Yap et al., 2011).”
  • The white-matter connectome at birth is highly organized and includes hub regions and connections similar to those observed in adults.

    “Overall, the white-matter connectome at birth is highly organized and includes hub regions and connections that are similar to those observed in adults48,49.”
  • Network maturation in the first two years after birth generally consists of increased network efficiency and integration, decreased segregation, and some changes in modularity, with most major hubs and modules in place by age two.

    “Network maturation in the first 2 years after birth generally consists of increased network efficiency and network integration [G], decreased network segregation [G], and some changes in the modularity48, 51, with most major hubs and modules in place by age 2 years52.”

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.
