Abstract

Oxytocin (OT) knock-out mice fail to recognize familiar conspecifics after repeated social exposures, despite normal olfactory and spatial learning abilities. OT treatment fully restores social recognition. Here we demonstrate that OT acts in the medial amygdala during the initial exposure to facilitate social recognition. OT given before, but not after, the initial encounter restores social recognition in OT knock-out mice. Using c-Fos immunoreactivity (Fos-IR) as a marker of neuronal activation in this initial encounter, we found similar neuronal activation in the wild-type (WT) and OT knock-out mouse in olfactory bulbs, piriform cortex, cortical amygdala, and the lateral septum. Wild-type, but not OT knock-out mice exhibited an induction of Fos-IR in the medial amygdala. Projections sites of the medial amygdala also failed to show a Fos-IR induction in the OT knock-out mice. OT knock-out, but not WT, mice showed dramatic increases in Fos-IR in the somatosensory cortex and the hippocampus, suggesting alternative processing of social cues in these animals. With site-specific injections of OT and an OT antagonist, we demonstrate that OT receptor activation in the medial amygdala is both necessary and sufficient for social recognition in the mouse.

  • Social discrimination is a complex behavior, and several other signaling molecules have been shown to play a role in social discrimination, including oxytocin and arginine vasopressin.

    “social discrimination is a complex behavior, and several other signaling molecules have been shown to play a role in social discrimination, including oxytocin [35–37] and arginine vasopressin [24, 38–40].”
  • A single treatment with oxytocin 24 hours after birth alters the expression of alloparental behavior in female prairie voles when they reach adulthood.

    “For example, a single treatment with OT 24 hours after birth alters the expression of alloparental behavior in female prairie voles when they reach adulthood [46].”

    From Oxytocin and the Neural Mechanisms Regulating Social Cognition and Affiliative Behavior (2009) · cites this paper as [46]

    The Animals and Social recognition tests sections describe male mice tested for social recognition, with adult females used as stimulus animals. Searches for neonatal oxytocin treatment and alloparental behavior in female prairie voles found no passage addressing the claimed result. (LLM, conf=0.76)

  • OTR knockout mice show social recognition deficits that can be remediated by oxytocin injections in medial amygdala.

    “OTR mouse knockouts show social recognition deficits that can be remediated by oxytocin injections in the medial amygdala [163].”
  • Infusion of an oxytocin receptor antagonist into the medial amygdala of wild-type mice recapitulates social memory deficits.

    “and infusions of an OXTR antagonist into the MeA of wild-type mice recapitulates those deficits in social memory (24).”
  • Infusion of oxytocin directly into the medial amygdala of oxytocin knockout mice rescues social amnesia.

    “Infusions of OT directly into the medial amygdala (MeA) of OT knockout mice rescues the social amnesia described above”

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.
