Growth of white matter in the adolescent brain: Myelin or axon?

Paus, Tomáš·2010·Brain and Cognition

Abstract

White matter occupies almost half of the human brain. It contains axons connecting spatially segregated modules and, as such, it is essential for the smooth flow of information in functional networks. Structural maturation of white matter continues during adolescence, as reflected in age-related changes in its volume, as well as in its microstructure. Here I review recent observations obtained with magnetic resonance imaging in typically developing adolescents and point out some of the known variations in structural properties of white matter vis-à-vis brain function in health and disease. I conclude by re-focusing the interpretations of MR-based studies of white matter from myelin to axon.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • There are corresponding increases in white matter during adolescence, thought to reflect increased myelination and axonal diameter, resulting in increased efficiency of impulse transduction.

    “There are corresponding increases in white matter, which is thought to reflect increased myelination and axonal diameter, resulting in increased efficiency of impulse transduction (Paus, 2010).”

  • Animal tracing studies suggest that tracts between the striatum and prefrontal regions are likely afferent, providing input to the striatum.

    “However, based on animal tracing studies, it is likely that the tracts between the striatum and prefrontal regions are afferent (i.e., providing input to the striatum) (58), suggesting the hypothesis that the reduction in impatience is due to top-down control.”

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.
