Abstract

The uncinate fasciculus is a major white matter tract that provides a crucial link between areas of the human brain that underlie emotion processing and regulation. Specifically, the uncinate fasciculus is the major direct fiber tract that connects the prefrontal cortex and the amygdala. The aim of the present study was to use a multi-modal imaging approach in order to simultaneously examine the relation between structural connectivity of the uncinate fasciculus and functional activation of the amygdala in a youth sample (children and adolescents). Participants were 9 to 19years old and underwent diffusion tensor imaging (DTI) and functional magnetic resonance imaging (fMRI). Results indicate that greater structural connectivity of the uncinate fasciculus predicts reduced amygdala activation to sad and happy faces. This effect is moderated by age, with younger participants exhibiting a stronger relation. Further, decreased amygdala activation to sad faces predicts lower internalizing symptoms. These results provide important insights into brain structure-function relationships during adolescence, and suggest that greater structural connectivity of the uncinate fasciculus may facilitate regulation of the amygdala, particularly during early adolescence. These findings also have implications for understanding the relation between brain structure, function, and the development of emotion regulation difficulties, such as internalizing symptoms.

  • In TD youth, amygdala reactivity to negative faces and images decreases with age, accompanied by greater structural and functional connectivity between amygdala and mPFC/rACC.

    “amygdala reactivity to negative faces and images decreases with age [21,33–36], and is accompanied by greater structural and functional connectivity between the amygdala and mPFC/rACC [25,33,34,36].”

    From Trauma, PTSD, and the Developing Brain (2017) · cites this paper as [36]

    The Results (§3.1; page unavailable) report decreasing amygdala activation to faces with age and increasing uncinate fasciculus FA, a measure of structural connectivity. The Introduction (§1; page unavailable) describes prior evidence of stronger negative amygdala–rACC functional connectivity with age, but this study found no significant age-related change in functional connectivity. The passages concern faces, not other negative images. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Most studies observe linear decreases in amygdala reactivity to affective stimuli with age.

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.
