Abstract

The development of social familiarity in rodents depends predominantly on olfactory cues and can critically influence reproductive success. Researchers have operationally defined this memory by a reliable decrease in olfactory investigation in repeated or prolonged encounters with a conspecific. Brain oxytocin (OT) and vasopressin (AVP) seem to modulate a range of social behaviour from parental care to mate guarding. Pharmacological studies indicate that AVP administration may enhance social memory, whereas OT administration may either inhibit or facilitate social memory depending on dose, route or paradigm. We found that male mice mutant for the oxytocin gene (Oxt-/-) failed to develop social memory, whereas wild-type (Oxt+/+) mice showed intact social memory. Measurement of both olfactory foraging and olfactory habituation tasks indicated that olfactory detection of non-social stimuli is intact in Oxt-/- mice. Spatial memory and behavioural inhibition measured in a Morris water-maze, Y-maze, or habituation of an acoustic startle also seemed intact. Treatment with OT but not AVP rescued social memory in Oxt-/- mice, and treatment with an OT antagonist produced a social amnesia-like effect in Oxt+/+ mice. Our data indicate that OT is necessary for the normal development of social memory in mice and support the hypothesis that social memory has a neural basis distinct from other forms of memory.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Increasing accumbal oxytocin receptor in female meadow voles was not sufficient to induce partner preference formation in this asocial species.

    “However, increasing accumbal OTR in female meadow voles was not sufficient to induce partner preference formation in this asocial species [45].”
  • Enhancing oxytocin receptor density in the nucleus accumbens of adult female prairie voles using a viral vector did not increase the proportion of females displaying alloparental care towards pups.

    “However, there was no difference between OTR viral injected and control groups in the proportion of females displaying alloparental behavior [45].”
  • OTR-enhanced female prairie voles took less time to form a partner preference than controls, indicating that higher levels of oxytocin receptor in the nucleus accumbens accelerates pair bond formation.

    “These OTR-enhanced females took less time to form a partner preference than controls, indicating that higher levels of OTR in the NAcc accelerates pair bond formation (Figure 4C).”
  • Previous work in social recognition has shown that mice show both habituation of olfactory responses directed toward an unfamiliar conspecific, and dishabituation, with a reinstatement of social sniffing, when a novel stimulus animal is presented.

    “Previous work in social recognition has shown that mice show both habituation of olfactory responses directed toward an unfamiliar conspecific, and dishabituation, with a reinstatement of social sniffing, when a novel stimulus animal is presented (Bluthe et al. 1993;Dluzen & Kreutzberg 1993;Ferguson et al. 2000;Kogan et al. 2000;Winslow & Camacho 1995).”
  • 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].”

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.
