Abstract

Despite its well-described role in female affiliation, the influence of oxytocin on male pairbonding is largely unknown. However, recent human studies indicate that this nonapeptide has a potent influence on male behaviors commonly associated with monogamy. Here we investigated the distribution of oxytocin receptors (OTR) throughout the forebrain of the socially monogamous male prairie vole (Microtus ochrogaster). Because males vary in both sexual and spatial fidelity, we explored the extent to which OTR predicted monogamous or non-monogamous patterns of space use, mating success and sexual fidelity in free-living males. We found that monogamous males expressed higher OTR density in the nucleus accumbens than non-monogamous males, a result that mirrors species differences in voles with different mating systems. OTR density in the posterior portion of the insula predicted mating success. Finally, OTR in the hippocampus and septohippocampal nucleus, which are nuclei associated with spatial memory, predicted patterns of space use and reproductive success within mating tactics. Our data highlight the importance of oxytocin receptor in neural structures associated with pairbonding and socio-spatial memory in male mating tactics. The role of memory in mating systems is often neglected, despite the fact that mating tactics impose an inherently spatial challenge for animals. Identifying mechanisms responsible for relating information about the social world with mechanisms mediating pairbonding and mating tactics is crucial to fully appreciate the suite of factors driving mating systems. This article is part of a Special Issue entitled Oxytocin, Vasopressin, and Social Behavior.

  • In voles, monogamous versus polygamous behavior is associated with higher density of dopamine D2 receptors in medial prefrontal cortex and oxytocin receptors in medial prefrontal cortex, NAcc, and caudate putamen.

    “Furthermore, in different species of voles, a monogamous, as opposed to polygamous, pattern of behavior is associated with a higher density of dopamine D2 receptors (D2R) in the medial prefrontal cortex (mPFC) (3) and of OXT receptors (OXTR) in mPFC, NAcc, and caudate putamen (4,5).”

    The General Discussion reports higher nucleus accumbens OTR density in monogamous than non-monogamous vole species. But the Results and Discussion found no prefrontal-cortex OTR difference between paired and single male prairie voles, and the paper does not report a mating-pattern difference in caudate-putamen OTR density. The D2-receptor claim is attached to a different citation. (LLM, conf=0.88)

  • Decreasing OXTR density in the nucleus accumbens using RNA interference inhibits partner preference formation.

    “Increasing OXTR density in the NAcc using viral-vector mediated gene transfer facilitates partner preference formation, while decreasing OXTR density in the same region using RNA interference inhibits such bonding (37–39).”
  • Increasing OXTR density in the nucleus accumbens using viral-vector mediated gene transfer facilitates partner preference formation.

    “Increasing OXTR density in the NAcc using viral-vector mediated gene transfer facilitates partner preference formation, while decreasing OXTR density in the same region using RNA interference inhibits such bonding (37–39).”
  • Differences in pair bonding behavior are mediated by OXTR variation.

    “and OXTR variation mediates individual differences in pair bonding behaviors (37–39).”
  • High OTR density in the NAc is linked to social monogamy in laboratory and free-living male prairie voles.

    “high OTR density in the NAc is linked to social monogamy not only in laboratory but also in free-living male prairie voles”

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.
