Quotes About Vasopressin

Human sexual and social behavior shares some similaries with that of rodents, but has some important differences as well. It shows much greater variability and individuality, for example, and is less closely tied to the olfactory system. At present, it is tempting to speculate that those of us with cheatin' hearts might have differences in brain dopamine, vasopressin, or oxytocin signaling when compared to our more faithful friends who have adopted the prairie vole lifestyle.

there's only one part of a man's anatomy that any potential mate should worry about measuring, and that is the length of his vasopressin receptor gene.

Obviously, oxytocin and vasopressin are the grooviest hormones in the universe. Pour them into the water supply, and people will be more charitable, trusting, and empathic. We'd be better parents and would make love, not war (mostly platonic love, though, since people in relationships would give wide berths to everyone else). Best of all, we'd buy all sorts of useless crap, trusting the promotional banners in stores once oxytocin starts spraying out of the ventilation system.

Oxytocin and vasopressin facilitate mother-infant bond formation and monogamous pair-bonding, decrease anxiety and stress, enhance trust and social affiliation, and make people more cooperative and generous. But this comes with a huge caveat—these hormones increase prosociality only toward an Us. When dealing with Thems, they make us more ethnocentric and xenophobic. Oxytocin is not a universal luv hormone. It's a parochial one.

Thus, oxytocin and vasopressin facilitate bonding between parent and child and between couples.fn10 Now for something truly charming that evolution has cooked up recently. Sometime in the last fifty thousand years (i.e., less than 0.1 percent of the time that oxytocin has existed), the brains of humans and domesticated wolves evolved a new response to oxytocin: when a dog and its owner (but not a stranger) interact, they secrete oxytocin.

Hormonal responses to various fetal and childhood experiences have epigenetic effects on genes related to the growth factor BDNF, to the vasopressin and oxytocin system, and to estrogen sensitivity. These effects are pertinent to adult cognition, personality, emotionality, and psychiatric health. Childhood abuse, for example, causes epigenetic changes in hundreds of genes in the human hippocampus.

As noted earlier, having a highly affectionate and responsive mother turns on different suites of genes, compared to being raised indifferently. Not surprisingly, neglect and trauma make social connection more difficult. These changes, too, are mediated by oxytocin, vasopressin, opioids, and dopamine.

was oxytocin and, especially in the male, vasopressin. These are two closely related biochemicals, technically neuropeptides (brain chemicals). This discovery alone ratchets up the relevance of the finding to the human condition: oxytocin is the most common gene-generated molecule in the human brain. In voles, it is the transformative switch. And not just in prairie voles, it turns

each is associated with different neurochemicals. Lust is associated primarily with the hormone testosterone in both men and women. Romantic love is linked with the natural stimulant dopamine and perhaps norepinephrine and serotonin. And feelings of male-female attachment are produced primarily by the hormones oxytocin and vasopressin. Moreover

One's desire to be alone, biologists have found, is partially genetic and to some degree measurable. If you have low levels of the pituitary peptide oxytocin—sometimes called the master chemical of sociability—and high quantities of the hormone vasopressin, which may suppress your need for affection, you tend to require fewer interpersonal relationships.
