Abstract

Post-traumatic stress disorder (PTSD) affects regions that support autobiographical memory (AM) retrieval, such as the hippocampus, amygdala and ventral medial prefrontal cortex (PFC). However, it is not well understood how PTSD may impact the neural mechanisms of memory retrieval for the personal past. We used a generic cue method combined with parametric modulation analysis and functional MRI (fMRI) to investigate the neural mechanisms affected by PTSD symptoms during the retrieval of a large sample of emotionally intense AMs. There were three main results. First, the PTSD group showed greater recruitment of the amygdala/hippocampus during the construction of negative versus positive emotionally intense AMs, when compared to controls. Second, across both the construction and elaboration phases of retrieval the PTSD group showed greater recruitment of the ventral medial PFC for negatively intense memories, but less recruitment for positively intense memories. Third, the PTSD group showed greater functional coupling between the ventral medial PFC and the amygdala for negatively intense memories, but less coupling for positively intense memories. In sum, the fMRI data suggest that there was greater recruitment and coupling of emotional brain regions during the retrieval of negatively intense AMs in the PTSD group when compared to controls.

  • Functional connectivity findings in adult PTSD are mixed, suggesting both greater and lower amygdala-mPFC connectivity to negative stimuli.

    “Functional connectivity findings in adult PTSD have been mixed, suggesting both greater [11–13] and lower [14] amygdala-mPFC connectivity to negative stimuli.”

  • St. Jacques et al. (2011) fMRI results indicate that PTSD patients have higher right amygdala activation during the construction of negatively intense autobiographical memory compared to a control group.

    “Subsequently, fMRI results obtained by St. Jacques et al. (2011) indicate that PTSD patients have higher amygdala activation (in the right amygdala) during the construction of negatively intense autobiographical memory, when compared to that of a control group.”
  • Insula responsivity to negative images in individuals with PTSD has been shown to be positively correlated with hyperarousal symptoms, re-experiencing symptoms and flashback intensity.

    “Indeed, insula responsivity to negative images in individuals with PTSD has previously been shown to be positively correlated with hyperarousal symptoms,19 re-experiencing symptoms63 and flashback intensity.64”

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.
