The structural integrity of an amygdala-prefrontal pathway predicts trait anxiety

Open access

Abstract

Here, we used diffusion tensor imaging (DTI) and showed that the strength of an axonal pathway identified between the amygdala and prefrontal cortex predicted individual differences in trait anxiety. A functional magnetic resonance imaging (fMRI) functional localizer that has been shown to produce reliable amygdala activation was collected in 20 psychiatrically healthy subjects. Voxelwise regression analyses using this fMRI amygdala reactivity as a regressor were performed on fractional anisotropy images derived from DTI. This analysis identified a white matter pathway between the amygdala and ventromedial prefrontal cortex. Individual differences in the structural integrity of this putative amygdala–prefrontal pathway were inversely correlated with trait anxiety levels (i.e., higher pathway strength predicted lower anxiety). More generally, this study illustrates a strategy for combining fMRI and DTI to identify individual differences in structural pathways that predict behavioral outcomes.

  • Projections to the nuclei of the amygdala reported in Ebeling and von Cramon (1992) refer to the entorhinal cortex and should not be mistaken for the amygdala proper.

    “Importantly, projections to the nuclei of the amygdala reported in Ebeling and von Cramon (1992) refers to the entorhinal cortex and should not be mistaken for the amygdala proper as is often done (Schmahmann and Pandya, 2006; Kim and Whalen, 2009).”

    The Discussion (page unavailable) says the uncinate fasciculus interconnects the amygdala and orbitofrontal lobe, explicitly citing Ebeling and von Cramon (1992). It does not make the claimed distinction that those projections concern the entorhinal cortex rather than the amygdala proper; its statement points the other way. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • These discrepancies may be due to the existence of adjacent tracts, such as the amygdalo-temporo or amygdala-prefrontal pathways, which may have been sometimes misattributed to the UF.

    “These discrepancies may be due to the existence of adjacent tracts, such as the amygdalo-temporo or amygdala-prefrontal pathways (Klinger and Gloor, 1960; Kim and Whalen, 2009) which may have been sometimes misattributed to the UF.”
  • Individual differences in amygdala responsivity have been associated with integrity of white matter fibers, including the uncinate fasciculus, in healthy control subjects.

    “Furthermore, individual differences in amygdala responsivity have been associated with integrity of white matter fibers, including the uncinate fasciculus in healthy control subjects (24), suggesting a relation between frontolimbic activity and structural connectivity.”
  • Connectivity analyses within anterior mPFC have revealed a ventrally mediated viscerolimbic affective and self-relevance network and a dorsally mediated cognitive network.

    “Connectivity analyses within anterior mPFC have revealed a ventrally mediated viscerolimbic affective and self-relevance network (with connections to amygdala, insula, and nucleus accumbens) and a dorsally mediated cognitive network (with connections to dorsolateral PFC and hippocampus) (Kim & Whalen, 2009; Price, Carmichael, & Drevets, 1996; Schmitz & Johnson, 2006).”
  • Reduced grey matter volume in the mPFC and weaker integrity of the uncinate fasciculus have been reported in adults with anxious temperament and anxiety disorders.

    “Structural abnormalities, such as reduced grey matter volume in the mPFC and weaker integrity of the uncinate fasciculus, have been reported in adults with anxious temperament and anxiety disorders24–28.”

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.
