Abstract

Background Somatic complaints and altered interoceptive awareness are common features in the clinical presentation of major depressive disorder (MDD). Recently, neurobiological evidence has accumulated demonstrating that the insula is one of the primary cortical structures underlying interoceptive awareness. Abnormal interoceptive representation within the insula may thus contribute to the pathophysiology and symptomatology of MDD. Methods We compared fMRI blood oxygenation level-dependent (BOLD) responses between twenty unmedicated adults with MDD and twenty healthy control participants during a task requiring attention to visceral interoceptive sensations and also assessed the relationship of this BOLD response to depression severity, as rated using the Hamilton Depression Rating Scale (HDRS). Additionally, we examined between-group differences in insula resting-state functional connectivity, and its relationship to HDRS ratings of depression severity. Results Relative to the healthy controls, unmedicated MDD subjects exhibited decreased activity bilaterally in the dorsal mid-insula cortex (dmIC) during interoception, as well as within a network of brain regions implicated previously in emotion and visceral control. Activity within the insula during the interoceptive attention task was negatively correlated with both depression severity and somatic symptom severity in depressed subjects. MDD also was associated with greater resting-state functional connectivity between the dmIC and limbic brain regions implicated previously in MDD, including the amygdala, subgenual prefrontal cortex, and orbitofrontal cortex. Moreover, functional connectivity between these regions and the dmIC was positively correlated with depression severity. Conclusions MDD and the somatic symptoms of depression are associated with abnormal interoceptive representation within the insula.

  • Individuals suffering from depression exhibit significantly decreased interoceptive sensitivity.

    “Indeed, recent studies indicate that individuals suffering from depression exhibit significantly decreased interoceptive sensitivity (Avery et al., 2014).”

    From Motivation in the Service of Allostasis: The Role of Anterior Mid-Cingulate Cortex (2019) · cites this paper as Avery et al., 2014

    The Results (Imaging Results; page unavailable) report significantly lower brain activity during interoceptive attention in depressed subjects, not a direct measure of interoceptive sensitivity. The Introduction (page unavailable) reports earlier findings of decreased heartbeat-perception accuracy in depression but cautions that those findings were mixed and difficult to interpret. Thus the source supports an interoceptive difference, but not the unqualified claim of significantly decreased sensitivity. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Qualitative synthesis found reduced activity in the insular cortex in major depressive disorder across multiple task modalities, with specific reductions in the posterior, dorsal mid- and anterior insula.

    “The most consistent finding was reduced activity in the insular cortex in MDD [36–38, 41, 42]. The effect was observed across multiple task modalities, including VIA, heartbeat, and CO2 reactivity, with specific reductions reported in the posterior, dorsal mid- and anterior insula.”

    From Neural correlates of altered interoception in depressive and anxiety disorders: a systematic review and meta-analysis (2026) · cites this paper as [36]

    The Results (Imaging Results; page not provided) report reduced bilateral dorsal mid-insula activity in MDD during heartbeat attention, and reduced activity in the same region during stomach and bladder attention. This supports the source’s contribution to the multi-citation sentence, but the paper does not report the claimed reductions in posterior and anterior insula or findings from VIA and CO2-reactivity tasks. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • All three whole-brain VIA studies reported decreased caudate nucleus activation in major depressive disorder.

    “All three studies reported decreased caudate nucleus activation in MDD.”

    From Neural correlates of altered interoception in depressive and anxiety disorders: a systematic review and meta-analysis (2026) · cites this paper as [36]

    The Results (Imaging Results; page not provided) report significantly lower right caudate BOLD activity in depressed subjects during attention to heartbeat sensations. This supports the finding for this study, but the paper does not establish that the other two studies also reported decreased caudate activation. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Avery et al. found that insula activity in individuals with major depressive disorder was negatively correlated with both affective and somatic symptom severity.

    “Supporting this view, Avery et al. found that insula activity in individuals with MDD was negatively correlated with both affective and somatic symptom severity, highlighting its potential role in linking disrupted bodily state processing to symptom expression [36].”

    From Neural correlates of altered interoception in depressive and anxiety disorders: a systematic review and meta-analysis (2026) · cites this paper as [36]

    The Results (Imaging Results; page not provided) report negative correlations between insula activity during heartbeat attention and both overall depression severity and somatic symptom severity in participants with MDD. They do not establish a separate correlation with affective symptom severity: only the HDRS somatization subscale was significantly related to dorsal mid-insula activity, while the other subscales were not. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Compromised interoceptive function is linked to psychiatric disorders including depression, anxiety, and addiction.

    “Clear links have been found between compromised interoceptive function and psychiatric disorders, including depression (Avery et al., 2013), anxiety (Paulus and Stein, 2010) and addiction (May et al., 2014).”

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.
