Abstract

BACKGROUND: Myelination of white matter in the brain continues throughout adolescence and early adulthood. This cortical immaturity has been suggested as a potential cause of dangerous and impulsive behaviors in adolescence. METHODOLOGY/PRINCIPAL FINDINGS: We tested this hypothesis in a group of healthy adolescents, age 12-18 (N = 91), who underwent diffusion tensor imaging (DTI) to delineate cortical white matter tracts. As a measure of real-world risk taking, participants completed the Adolescent Risk Questionnaire (ARQ) which measures engagement in dangerous activities. After adjusting for age-related changes in both DTI and ARQ, engagement in dangerous behaviors was found to be positively correlated with fractional anisotropy and negatively correlated with transverse diffusivity in frontal white matter tracts, indicative of increased myelination and/or density of fibers (ages 14-18, N = 60). CONCLUSIONS/SIGNIFICANCE: The direction of correlation suggests that rather than having immature cortices, adolescents who engage in dangerous activities have frontal white matter tracts that are more adult in form than their more conservative peers.

  • Some studies have found that same-aged individuals with more well-developed connections between cortical and subcortical areas engage in relatively more risk taking.

    “some studies have also found that same-aged individuals with more well-developed connections between cortical and subcortical areas engage in relatively more risk taking (Berns et al., 2009, DeWitt et al., 2014).”

    The Results report that, among adolescents aged 14–18, greater dangerous-behavior scores were associated with white matter measures interpreted as more mature frontal tracts after adjustment for age and sex. The Discussion identifies some associated fibers as pathways linking the cortex with the brainstem and spinal cord, but also says no correlation was found for subcortical white matter tracts. The claim is therefore supported for age-matched risk taking and frontal white matter maturity, but overgeneralizes the finding as better-developed connections between cortical and subcortical areas. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • After accounting for age-related rises in both, greater white matter maturity tracked with more risky behavior.

    “increased WM maturity was associated with increased engagement in risky behaviors, adjusting for known age-related increases in both measures [57].”
  • White matter structural maturity correlates with greater, not lesser, risk-taking.

    “structural maturity of white matter is correlated with more, not less, risk-taking.”

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.
