Abstract

Oxytocin (OT) modulates social behavior in primates and many other vertebrate species. Studies in non‐primate animals have demonstrated that, in addition to influencing activity within individual brain areas, OT influences functional connectivity across networks of areas involved in social behavior. Previously, we used fMRI to image brain function in human subjects during a dyadic social interaction task following administration of either intranasal oxytocin (INOT) or placebo, and analyzed the data with a standard general linear model. Here, we conduct an extensive re‐analysis of these data to explore how OT modulates functional connectivity across a neural network that animal studies implicate in social behavior. OT induced widespread increases in functional connectivity in response to positive social interactions among men and widespread decreases in functional connectivity in response to negative social interactions among women. Nucleus basalis of Meynert, an important regulator of selective attention and motivation with a particularly high density of OT receptors, had the largest number of OT‐modulated connections. Regions known to receive mesolimbic dopamine projections such as the nucleus accumbens and lateral septum were also hubs for OT effects on functional connectivity. Our results suggest that the neural mechanism by which OT influences primate social cognition may include changes in patterns of activity across neural networks that regulate social behavior in other animals.

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

  • No effects of intranasal OXT treatment were observed in women when they were not cooperating.

    “Conversely, no effects of intranasal OXT treatment were observed in women when they were not cooperating.”

    From Convergence of oxytocin and dopamine signalling in neuronal circuits: Insights into the neurobiology of social interactions across species (2024) · cites this paper as Rilling et al., 2018

    Results §3.1 reports no effect on individual-region activation in women for CD outcomes, but Results §3.2 reports 19 oxytocin-modulated functional connections in women for those outcomes. Methods §2.3 defines CD as the woman cooperating while her partner defects, so it does not describe women themselves not cooperating. The paper therefore does not support the unqualified claim of no effects. (LLM, conf=0.85)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Intranasal OXT treatment had no discernible impact on brain activity in men when they were cooperating.

    “However, intranasal OXT treatment had no discernible impact on brain activity in men when they were cooperating.”

    From Convergence of oxytocin and dopamine signalling in neuronal circuits: Insights into the neurobiology of social interactions across species (2024) · cites this paper as Rilling et al., 2018

    Results §3.1 reports no effect of oxytocin on activation in any individual region in men following reciprocated cooperation (CC outcomes). But Results §3.2 reports that oxytocin altered 23 functional connections in men following those outcomes, so the broader claim of no discernible impact on brain activity overstates the finding. Page numbers were not available in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Intraperitoneal OXT injection significantly influenced trial outcomes, leading to a decrease in defection and an increase in cooperation.

    “Notably, an intraperitoneal OXT injection significantly influenced the trial outcomes, leading to a decrease in defection and an increase in cooperation (Donovan et al., 2020), a pattern similar to what has been observed in humans (Rilling et al., 2018).”

    From Convergence of oxytocin and dopamine signalling in neuronal circuits: Insights into the neurobiology of social interactions across species (2024) · cites this paper as Rilling et al., 2018

    The Introduction reports that intranasal oxytocin has been associated with trust and cooperation in humans, supporting the broad comparison. But this paper’s Discussion reports sex-dependent neural responses to cooperation and defection outcomes, not a demonstrated decrease in defection and increase in cooperation in its participants. Its human treatment was intranasal, not intraperitoneal. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Reduced AMY and VTA activation after a non-cooperative outcome was found in men.

    “In addition, reduced AMY and VTA activation after a non-cooperative outcome was found in this group (Rilling et al., 2018).”

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.
