Genes, brains and mammalian social bonds

Abstract

Recent studies of monogamous species have revealed the role of the neuropeptides oxytocin and vasopressin in activating reward mechanisms of the brain that are involved in establishing partner recognition and selective 'bonding'. The evolutionary history of these findings resides, at a mechanistic level, in the reciprocal bonding between mother and infant that is common to all mammals. However, in Old World primates, where mother and infant alone would not survive, living in large social groups brings extended family relationships and provides for alloparenting. This has required the emancipation of parenting behaviour from the constraints of hormonal state and the evolution of large brains for decision making that was previously restricted and determined by hormonal state. How this has been achieved, what conserved mechanisms underpin social bonding, and what genetic and mechanistic changes have occurred in the evolution of social bonds are the issues addressed here.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Sharers may experience a mutual increase in positive attitude, resulting in the promotion of stronger social bonds and longer-term benefits of more frequent cooperation.

    “Also, as oxytocin is thought to act on positive feedback circuits [16,17,21], sharers may experience a mutual increase in positive attitude [15,79,80], resulting in the promotion of stronger social bonds and longer-term benefits of more frequent cooperation [23,26,80].”
  • Comparative study can show the processes by which competing behavioral and physiological demands on common neural systems interact and constrain each other during evolution.

    “Comparative study can show the processes by which competing behavioral and physiological demands on common neural systems interact and constrain each other during evolution (Curley and Keverne, 2005; Goodson and Thompson, 2010).”
  • Interactions of the oxytocinergic system with behavior, social environment, and endocrinological environment may be more nuanced in primates than rodents.

    “Research indicates that interactions of the oxytocinergic system with behavior, social environment, and endocrinological environment may be more nuanced in primates than rodents (Curley and Keverne, 2005).”

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.
