Modulating social behavior with oxytocin: How does it work? What does it mean?

Open access
Churchland, Patricia S., Winkielman, Piotr·2012·Hormones and Behavior

Abstract

Among its many roles in body and brain, oxytocin influences social behavior. Understanding the precise nature of this influence is crucial, both within the broader theoretical context of neurobiology, social neuroscience and brain evolution, but also within a clinical context of disorders such as anxiety, schizophrenia, and autism. Research exploring oxytocin's role in human social behavior is difficult owing to its release in both body and brain and its interactive effects with other hormones and neuromodulators. Additional difficulties are due to the intricacies of the blood-brain barrier and oxytocin's instability, which creates measurement issues. Questions concerning how to interpret behavioral results of human experiments manipulating oxytocin are thus made all the more pressing. The current paper discusses several such questions. We highlight unresolved fundamental issues about what exactly happens when oxytocin is administered intranasally, whether such oxytocin does in fact reach appropriate receptors in brain, and whether central or peripheral influences account for the observed behavioral effects. We also highlight the deeper conceptual issue of whether the human data should be narrowly interpreted as implicating a specific role for oxytocin in complex social cognition, such a generosity, trust, or mentalizing, or more broadly interpreted as implicating a lower-level general effect on general states and dispositions, such as anxiety and social motivation. Using several influential studies, we show how seemingly specific, higher-level social-cognitive effects can emerge via a process by which oxytocin's broad influence is channeled into a specific social behavior in a context of an appropriate social and research setting. This article is part of a Special Issue entitled Oxytocin, Vasopressin, and Social Behavior.

  • The pre-study odds of studies investigating the effect of intranasal oxytocin are low, primarily due to limitations in deep brain penetration of oxytocin when administered intranasally.

    “Although the idea that manipulating OT in humans could influence social behavior is supported by rigorous animal research, we argue that the pre-study odds of studies investigating the effect of IN-OT still would be low, primarily due to limitations in deep brain penetration of OT when administered intranasally (2, 19).”

    From Statistical and Methodological Considerations for the Interpretation of Intranasal Oxytocin Studies (2016) · cites this paper as [2]

    Section 2B questions whether intranasal oxytocin reaches brain receptor sites in sufficient amounts and notes its poor penetration across the blood–brain barrier. It does not establish that intranasal delivery has limited deep-brain penetration or assess the pre-study odds of such studies; those are stronger claims than the paper makes. (LLM, conf=0.84)

  • Oxytocin is present in a large number of animal species from reptiles to mammals and is intimately associated with social, sexual, and reproductive behaviors including mating and childbirth.

    “The neuropeptide oxytocin is present in a large number of animal species from reptiles—in the form of vasotocin, an evolutionary precursor—to mammals, encompassing the primates, and is intimately associated with social, sexual, and reproductive behaviors including mating and childbirth.”

    From Could intranasal oxytocin be used to enhance relationships? Research imperatives, clinical policy, and ethical considerations (2013) · cites this paper as [34]

    The Introduction links oxytocin to childbirth, mate attachment, and social recognition; §2A also discusses its release during mating. Our copy does not establish its presence across species from reptiles to primates or identify vasotocin as an evolutionary precursor. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Oxytocin produced by the hypothalamus plays a dual role: as a hormone in the peripheral bloodstream controlling milk letdown, uterine contraction, and cervical dilation; and as a neurotransmitter in the central nervous system influencing social, behavioral, and motivational states via receptors in the hippocampus, amygdala, nucleus accumbens, and elsewhere.

    “Produced by the hypothalamus, oxytocin plays a dual role in modulating a wide range of essential processes: it acts as a hormone when released into the peripheral bloodstream, controlling functions such as milk letdown, uterine contraction, and cervical dilation during parturition in females; and it acts as a neurotransmitter when released into the central nervous system, influencing social, behav”

  • Oxytocin has a role in regulating complex social behavior, including parental care, social bonding and social cognition in general.

    “More recently, attention has turned to its role in regulating complex social behavior, including parental care, social bonding and social cognition in general (1–6).”
  • It is unclear to what extent peripheral oxytocin measurements reflect central oxytocin concentrations.

    “Nevertheless, it is currently unclear to what extent peripheral measurements reflect central OXT concentrations (25).”

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.
