The functional architecture of the infant brain as revealed by resting-state fMRI

Abstract

The functional network topology of the adult human brain has recently begun to be noninvasively mapped using resting-state functional connectivity magnetic resonance imaging and described using mathematical tools originating from graph theory. Previous studies have revealed the existence of disproportionally connected brain regions, so called cortical hubs, which act as information convergence zones and supposedly capture key aspects of how the brain's architecture supports human behavior and how it is affected by disease. In this study, we present results showing that cortical hubs and their associated cortical networks are largely confined to primary sensory and motor brain regions in the infant brain. Our findings in infants stand in stark contrast to the situation found in adults where the majority of cortical hubs and hub-related networks are located in heteromodal association cortex. Our findings suggest that the functional network architecture in infants is linked to support tasks that are of a perception-action nature.

  • Neonatal hubs primarily involve early sensorimotor, visual, and limbic regions.

    “whereas neonatal hubs primarily involve early sensorimotor, visual, and limbic regions (De Asis-Cruz et al., 2015; Fransson et al., 2011; Gao et al., 2011).”
  • Hub configurations are robustly evident after birth.

  • In adulthood, high strength and betweenness hubs are largely located within default mode, attentional, sensorimotor, and visual areas.

    “high strength and betweenness hubs in adulthood are largely located within within the default mode, attentional, sensorimotor, and visual areas (Cao et al., 2014; Fransson et al., 2011; Grayson et al., 2014; Hwang et al., 2013)”
  • Primary functional networks, including sensorimotor, visual and auditory networks, develop first and show adult-like topologies in premature babies at term age and in full-term newborns.

    “Specifically, primary functional networks, including the sensorimotor, visual, and auditory networks, develop first and show adult-like topologies in premature babies at term age86, 89, 92, 93 and in full-term newborns6, 90, 91.”
  • The shift in behavioral strategies may reflect maturation of connections between default mode network regions, known to be involved in hetero-modal integration and processing of socially relevant stimuli and interactions, with primary visual and sensory-motor regions along with higher association areas distributed throughout prefrontal and parietal cortex.

    “This shift in behavioral strategies may reflect maturation of connections between default mode network regions, known to be involved in hetero-modal integration as well as processing of socially relevant stimuli and interactions, with primary visual and sensory-motor regions along with higher association areas distributed throughout the prefrontal and parietal cortex (Buckner et al. 2008; Fransson”

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.
