Abstract

Oxytocin receptors (OXTR) in the nucleus accumbens (NAcc) promote alloparental behavior and partner preference formation in female prairie voles. Within the NAcc there is significant individual variation in OXTR binding and virgin juvenile and adult females with a high density of OXTR in the NAcc display an elevated propensity to engage in alloparental behavior toward novel pups. Over-expression of OXTR in the NAcc of adult female prairie voles using viral vector gene transfer facilitates partner preference formation, but has no effect on alloparental behavior, even though OXTR antagonists infused into the NAcc blocks both behaviors. We therefore hypothesized that long-term increases in OXTR signaling during development may underlie the relationship between adult OXTR density in the NAcc and alloparental behavior. To test this hypothesis, we used viral vector gene transfer to increase OXTR density in the NAcc of prepubertal, 21day old female prairie voles and tested for both alloparental behavior and partner preference formation as adults. Consistent with a developmental impact of OXTR signaling, adults over-expressing OXTR from weaning display both increased alloparental behavior and partner preference formation. Thus, the relatively acute impact of elevated OXTR signaling in the NAcc on partner preference formation previously reported appears to be dissociable from the effects of longer term, developmentally relevant OXTR signaling necessary for modulating alloparental behavior. These results are consistent with the hypothesis that oxytocin can have both long-term "organizational" effects as well as acute "activational" effects on affiliative behaviors.

  • Viral knockdown of OXTRs within the NAc of voles disrupts partner preference formation and alloparental behavior; increasing OXTR expression in the NAc facilitates pair bonding and maternal care.

    “Additionally, viral knockdown of OXTRs within the NAc of voles disrupts partner preference formation and alloparental behavior; however, pair bonding and maternal care are facilitated when OXTR expression in the NAc is increased, suggesting a direct role of NAc OXTRs in driving affiliative behavior [15,140].”

    From The Neurobiology of Love and Pair Bonding from Human and Animal Perspectives (2023) · cites this paper as [140]

    The Introduction and Discussion report that blocking NAc OXTRs with antagonists disrupts alloparental behavior and partner preference formation, not that viral knockdown does so. The paper's experiment supports the other half of the claim: viral OXTR overexpression in prepubertal female prairie voles increased partner preference formation and alloparental care in adulthood. The care measured was toward pups in females that were not mothers, rather than maternal care by mothers; page numbers were not available in our copy. (LLM, conf=0.90)

  • Prairie voles are highly nurturing, and virgin females can display spontaneous levels of maternal care depending on density of nucleus accumbens oxytocin receptors.

  • 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).”

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.
