Abstract

BACKGROUND: Moral injury (MI) is consistently associated with adverse mental health outcomes, including the development of posttraumatic stress disorder (PTSD) and suicidality. METHODS: We investigated neural activation patterns associated with MI event recall using functional magnetic resonance imaging in participants with military and public safety-related PTSD, relative to civilian MI-exposed controls. RESULTS: MI recall in the PTSD as compared to control group was associated with increased neural activation among salience network nodes involved in viscerosensory processing and hyperarousal (right posterior insula, dorsal anterior cingulate cortex; dACC), regions involved in defensive responding (left postcentral gyrus), and areas responsible for top-down cognitive control of emotions (left dorsolateral prefrontal cortex; dlPFC). Within the PTSD group, measures of state and trait shame correlated negatively with activity among default mode network regions associated with self-related processing and moral cognition (dorsomedial prefrontal cortex; dmPFC) and salience network regions associated with viscerosensory processing (left posterior insula), respectively. CONCLUSIONS: These findings suggest that MI event processing is altered in military and public safety-related PTSD, relative to MI-exposed controls. Here, it appears probable that as individuals with PTSD recall their MI event, they experience a surge of blame-related processing of bodily sensations within salience network regions, including the right posterior insula and the dACC, which in turn, prompt regulatory strategies at the level of the left dlPFC aimed at increasing cognitive control and inhibiting emotional affect. These results are consistent with previous findings showing enhanced sensory processing and altered top-down control in PTSD samples during autobiographical memory recall.

  • Investigations of morally salient autobiographical recall report atypical posterior DMN activation, altered connectivity with sensorimotor and midbrain regions, and associations between shame intensity and dorsomedial prefrontal activity.

    “Investigations of morally salient autobiographical recall report atypical posterior DMN activation, altered connectivity with sensorimotor and midbrain regions, and associations between shame intensity and dorsomedial prefrontal activity—patterns broadly consistent with intensified moral self-focus and difficulties integrating emotionally charged experiences into coherent narratives (40, 41, 52).”

    From The therapeutic role of self-transcendence in moral injury recovery: theory, mechanisms, and clinical implications (2026) · cites this paper as [40]

    The Discussion (§4) and neural-correlates-of-shame section (§4.2) report that greater shame during morally injurious event recall was associated with reduced activity in a dorsomedial prefrontal region among participants with PTSD. The Neuroimaging Results (§3.2) describe only a trending, not statistically significant, interaction in the posterior cingulate cortex. The paper does not report altered connectivity with sensorimotor and midbrain regions during this recall task. (LLM, conf=0.88)

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.
