The neurobiology of attachment

Insel, Thomas R., Young, Larry J.·2001·Nature Reviews Neuroscience

Abstract

It is difficult to think of any behavioural process that is more intrinsically important to us than attachment. Feeding, sleeping and locomotion are all necessary for survival, but humans are, as Baruch Spinoza famously noted, "a social animal" and it is our social attachments that we live for. Over the past decade, studies in a range of vertebrates, including humans, have begun to address the neural basis of attachment at a molecular, cellular and systems level. This review describes some of the important insights from this work.

  • Attachment hyperactivation and deactivation strategies have been shown to inhibit other behavioral systems involved in resilience, such as exploration, affiliation, and caregiving, which might partially explain difficulties entering lasting relationships and intergenerational transmission of psychopathology.

    “Moreover, they have also been shown to inhibit other behavioral systems that are involved in resilience, such as exploration, affiliation, and caregiving (Insel & Young, 2001; Mikulincer & Shaver, 2007; Neumann, 2008), which might also partially explain these individuals' difficulties in entering lasting relationships (including relationships with mental health care professionals) and the”
  • Oxytocin and vasopressin inhibit aversion of female and male rodents to infant pups and lead to affiliative behaviors including caregiving.

    “For instance, oxytocin and vasopressin have been shown to inhibit aversion of both female and male rodents to infant pups, as well as leading to a number of affiliative behaviors, including caregiving behavior (Insel & Young, 2001).”
  • Experiments in prairie voles reveal central roles for oxytocin in modulating emotional and social behaviors.

    “Experiments in prairie voles have revealed central roles for oxytocin in modulating a variety of emotional and social behaviors [164–166].”
  • Research has repeatedly implicated OT as one of the key hormones involved in parent-infant bonding in mammals, as well as in a range of social and affiliative behaviors.

    “Research has repeatedly implicated the neuropeptide oxytocin (OT) as one of the key hormones involved in parent-infant bonding in mammals, as well as in a range of social and affiliative behaviors (3–7).”

  • Healthy maternal sensitivity is characterized by the ability to reliably recognize and respond to infant cues, thus initiating appropriate caregiving responses.

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.
