0000002628 00000 n Life’s most important experiences – sexual experiences, birth, the presence or absence of sensitive parenting, exposure to hormones in early life, extreme stress and traumas – are all “epigenetic” events regulated by molecular changes with long lasting effects on the genome. Physiological substrates of mammalian monogamy: The prairie vole model. However, it has taken decades and the help of prairie voles to untangle these relationships. 0000052671 00000 n 0000031014 00000 n It was all started by a mouse,” But we now understand that the traits of social monogamy are a kind of syndrome with shared neurobiological underpinnings. The presence of vasopressin receptor 1A (V1aR) in the ventral forebrain is associated with pair bonding, which is necessary for monogamy. 0000010463 00000 n But of par-ticular importance for understanding the biology of monogamy is the fact that not all voles are monogamous. 0000035546 00000 n 0000063475 00000 n 0000003376 00000 n While the stay-at-home prairie voles cuddle in their burrows, montane males mate indistriminately with one female after another. The voles, it turns out, mated every hour. Field biologists have noted that the male prairie vole pairs off with a single female, probably for life. None of this is shocking. The absence or loss of love creates vulnerability to substance abuse, depression and other forms of mental and physical illness. In both nature and in the laboratory small field mice, called prairie voles form life-long social bonds. endstream endobj 83 0 obj<> endobj 85 0 obj<> endobj 86 0 obj<>/ProcSet[/PDF/Text]/ExtGState<>>> endobj 87 0 obj<> endobj 88 0 obj<> endobj 89 0 obj<> endobj 90 0 obj<> endobj 91 0 obj<>stream Some individuals were sexually monogamous, but when viewed at the level of a species, sexual monogamy was rare or non-existent. 2017 These hormones were released by social experiences, including sexual interactions and even the presence of a baby. 144, No. Prairie vole families are bound together by invisible social bonds. 0000023469 00000 n 2014 Our terminology had to be adjusted to admit that what we were observing was more accurately termed “social monogamy.”. Scientists Look to Prairie Vole Brains to Understand Monogamy. Before delving into the specifics of the team's investigation, it may be helpful to define monogamy. �ŷ��j��'�����,�8(�����L#��� ����D��IA9���K��������]{#3�]�[�7"���=^� ZR�'����2�0C#��## �0,�DoGH*4�+��y�����=%��s-D https://www.ncbi.nlm.nih.gov/pubmed/?term=Carter+love+and+fear, The monogamy paradox: What do love and sex have to do with it?

This vast difference in lifestyle may come down to a single brain hormone, vasopressin, which in the human body is more commonly associated with regulation of water content. Selective attachments, and well as parenting, are supported by a comparatively simple brain and ancient neural and endocrine pathways. Science News. Extended families form around the original pair, as prairie vole fathers and then older offspring remain in the natal nest, scrupulously avoiding incest. If the problem persists, please try again in a little while. 0000059129 00000 n And the effect isn't just … Hormonal ties that bind. 0000010554 00000 n However, prairie voles have taught us that love is constructed from biological mechanisms that are shared with other mammals.

At the same time, vasopressin may trigger another characteristic behavior--that of the father prairie vole caring for his pups, another group of investigators finds. To test the theory, the researchers tried to prevent that behavioral change with a chemical blockade, something that would stop the action of vasopressin or oxytocin. Science News, Magazine article An unknown error has occurred. (Walt Disney), The term monogamy is derived from the Greek for a single wedding or ritual, and does not speak to sexual choices. 1993; Tamarin 1985). As we searched for a mechanism for social monogamy, we found in both male and female voles that pair bonds were cemented by powerful molecules synthesized in the brain. http://edition.pagesuite-professional.co.uk/html5/reader/production/default.aspx?pubname=&edid=14e30abb-c333-43f5-b63d-31e069aee049&pnum=182, Bloomington, IN 47405 Insel and his colleagues began by observing mate-guarding behavior, the dramatic change that overcomes a mle prairie vole when an intruder enters his family's burrow. Researchers believe that a chemical produced in the brain may turn on monogamous behavior. You have entered an incorrect email address! The researchers found that compared to polygamous voles, prairie voles' brains had different distributions of certain receptors, proteins that sit on the surface of nerve cells. In turn these brain-derived chemicals regulate social engagement, pair bond formation and parental behaviour. 0000001826 00000 n Males of this species are amazing parents involved in all aspects of care of the young except nursing. 82 0 obj<> endobj In fact, prairie voles are teaching us that the genes regulating receptors for oxytocin and vasopressin can be switched off or on across the life cycle.

Considered across the lifespan, many humans have more than one sexual partner. Furthermore, nature is conservative and the same hormones are used over and over again across the life cycle and in different species of mammals, where they support variations in social behaviour and aggression across species and individuals, as well as sex differences in behaviour.
