Abstract

Here we discuss the origins of diversity in social behavior by highlighting research using the socially monogamous prairie vole.Prairie voles display a rich social behavioral repertoire involving pair bonding and consoling behavior that are not observed in typical laboratory species.Oxytocin and vasopressin play critical roles in regulating pair bonding and consoling behavior.Oxytocin and vasopressin receptors show remarkable diversity in expression patterns both between and within species.Receptor expression patterns are associated with species differences in social behaviors.Variations in receptor genes have been linked to individual variation in expression patterns.We propose that "evolvability" in the oxytocin and vasopressin receptor genes allows for the repurposing of ancient maternal and territorial circuits to give rise to novel social behaviors such as pair bonding, consoling and selective aggression.We further propose that the evolvability of these receptor genes is due to their transcriptional sensitivity to genomic variation.This model provides a foundation for investigating the molecular mechanisms giving rise to the remarkable diversity in social behaviors found in vertebrates.

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

  • Prairie voles and other monogamous species express high levels of oxytocin receptors in the nucleus accumbens while non-monogamous species do not.

    “Prairie voles and other monogamous species, including marmosets and humans express high levels of oxytocin receptors (OXTR) in the NAc while non-monogamous species, such as laboratory mice and rhesus macaques, do not 24–26.”

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.
