Abstract

Maternal stress can shape long-term child neurodevelopment beginning in utero. One mechanism by which stress is transmitted from mothers to their offspring is via alterations in maternal cortisol, which can cross the placenta and bind to glucocorticoid receptor-rich regions in the fetal brain, such as the hippocampus. Although prior studies have demonstrated associations between maternal prenatal stress and cortisol levels with child brain development, we lack information about the extent to which these associations originate prior to birth and prior to confounding postnatal influences. Pregnant mothers (n = 77) completed questionnaires about current perceived stress, depressive symptoms, and anxiety symptoms, provided three to four salivary cortisol samples, and completed a fetal resting-state functional MRI scan during their second or third trimester of pregnancy (mean gestational age = 32.8 weeks). Voxelwise seed-based connectivity analyses revealed that higher prenatal self-reported distress and higher maternal cortisol levels corresponded to dissociable differences in fetal hippocampal functional connectivity. Specifically, self-reported distress was correlated with increased positive functional coupling between the hippocampus and right posterior parietal association cortex, while higher maternal cortisol was associated with stronger positive hippocampal coupling with the dorsal anterior cingulate cortex and left medial prefrontal cortex. Moreover, the association between maternal distress, but not maternal cortisol, on fetal hippocampal connectivity was moderated by fetal sex. These results suggest that prenatal stress and peripheral cortisol levels may shape fetal hippocampal development through unique mechanisms.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The association between increased coupling with the medial prefrontal area and dorsal anterior cingulate cortex and maternal cortisol is moderated by fetal sex, but the association with right posterior parietal cortex is not.

    “Importantly, the latter association, but not the former, is moderated by fetal sex.”

    From Brain structural and functional outcomes in the offspring of women experiencing psychological distress during pregnancy (2024) · cites this paper as [107]

    The Results (section 3.3) state the opposite of the attributed claim: fetal sex did not moderate the associations between maternal cortisol and hippocampal connectivity with the dACC or mPFC. It did moderate the association between maternal distress and hippocampal–posterior parietal connectivity. (LLM, conf=0.94)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Increases in hippocampal connectivity due to elevated maternal stress and cortisol have been reported.

    “Recently, increases in hippocampal connectivity due to elevated maternal stress and cortisol have also been reported [107].”

    From Brain structural and functional outcomes in the offspring of women experiencing psychological distress during pregnancy (2024) · cites this paper as [107]

    The Discussion reports stronger fetal hippocampal connectivity associated with higher maternal cortisol and, separately, greater self-reported distress. The Conclusions suggest a possible strengthening mechanism, but the study reports associations rather than establishing that stress or cortisol caused the increases implied by “due to.” (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Increased coupling with the medial prefrontal area and dorsal anterior cingulate cortex is related to increased maternal cortisol.

    “Increased connectivity to the right posterior parietal cortex is associated with elevated maternal stress while increased coupling with the medial prefrontal area and dorsal anterior cingulate cortex is related to increased maternal cortisol.”
  • Increased connectivity to the right posterior parietal cortex is associated with elevated maternal stress.

    “Increased connectivity to the right posterior parietal cortex is associated with elevated maternal stress while increased coupling with the medial prefrontal area and dorsal anterior cingulate cortex is related to increased maternal cortisol.”

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.
