Abstract

The formation of enduring relationships between adult mates (i.e., pair bonds) is an integral aspect of human social behavior and has been implicated in both physical and psychological health. However, due to the inherent complexity of these bonds and the relative rarity with which they are formed in other mammalian species, we know surprisingly little about their underlying neurobiology. Over the past few decades, the prairie vole (Microtus ochrogaster) has emerged as an animal model of pair bonding. Research in this socially monogamous rodent has provided valuable insight into the neurobiological mechanisms that regulate pair bonding behaviors. Here, we review these studies and discuss the neural regulation of three behaviors inherent to pair bonding: the formation of partner preferences, the subsequent development of selective aggression toward unfamiliar conspecifics, and the bi-parental care of young. We focus on the role of vasopressin, oxytocin, and dopamine in the regulation of these behaviors, but also discuss the involvement of other neuropeptides, neurotransmitters, and hormones. These studies may not only contribute to the understanding of pair bonding in our own species, but may also offer insight into the underlying causes of social deficits noted in several mental health disorders.

  • The bonding effects of oxytocin and vasopressin in prairie voles are mediated by dopamine release, particularly in the VTA and NAcc.

    “Their effects on bonding are mediated via interactions with dopamine (DA) release, particularly in the ventral tegmental area (VTA) and nucleus accumbens (NAcc).”

    From Oxytocin enhances brain reward system responses in men viewing the face of their female partner (2013) · cites this paper as [2]

    Section 8, “Neurochemical/hormone interactions,” reports that oxytocin and vasopressin interact with dopamine systems in partner-preference formation, including oxytocin–dopamine receptor interactions in the NAcc. Section 4.3 reports increased NAcc dopamine during mating. The paper does not establish that both hormones’ bonding effects are mediated by dopamine release in the VTA and NAcc; its VTA discussion concerns other neurotransmitters, and its vasopressin–dopamine example involves the ventral pallidum. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In prairie voles, mating releases oxytocin or vasopressin, and these neuropeptides promote partner bond formation.

    “In prairie voles, partner bonds are formed after the neuropeptides oxytocin (OXT) or arginine vasopressin (AVP) are released in the brain during mating.”

    From Oxytocin enhances brain reward system responses in men viewing the face of their female partner (2013) · cites this paper as [2]

    Section 4.2 reports increased oxytocin in the nucleus accumbens during sociosexual experience and evidence that both oxytocin and vasopressin promote partner preferences. It says mating-related changes in males *suggest* vasopressin release, rather than establishing that release as a fact; the claim also specifies mating where the oxytocin finding says sociosexual experience. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • The parvocellular AVP/OT system is sexually dimorphic, steroid hormone sensitive, and fundamental for the coordination of affiliative and social behaviors including courtship, pair bonding, empathy, reciprocity, trust, and context-specific aggression.

    “The parvocellular system sends projections to the median eminence and throughout the brain and is sexually dimorphic, steroid hormone sensitive, and fundamental for the coordination of affiliative and social behaviors including courtship, pair bonding, empathy, reciprocity, trust, and context-specific aggression (1–4).”

  • The density of ERα markedly differs across prosocial and asocial species and is directly related to the degree to which individuals and species are prosocial.

    “This view is consistent with the observation that the density of ERα markedly differs across prosocial and asocial species and is directly related to the degree to which individuals and species are prosocial (3, 137, 138).”

    From Endocrine Disruption of Vasopressin Systems and Related Behaviors (2017) · cites this paper as [3]

    Section 7 reports that increased ERα expression in male prairie voles was associated with reduced social affiliation and describes an inverse relationship between regional ERα expression and social behavior. It does not report marked ERα-density differences between prosocial and asocial species; the cross-species receptor comparisons in Section 3 concern other receptors. Page numbers are unavailable in our copy. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • In some mammalian species, oxytocin is involved in forming partner bonds through interaction with brain dopamine reward systems.

    “The evolutionarily conserved neuropeptide oxytocin (OXT) is associated with the formation of partner bonds in some species via interactions with brain dopamine reward systems.”

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.
