In the new issue of Nature, the neuroscientist Larry Young offers a grand unified theory of love. After analyzing the brain chemistry of mammalian pair bonding — and, not incidentally, explaining humans’ peculiar erotic fascination with breasts — Dr. Young predicts that it won’t be long before an unscrupulous suitor could sneak a pharmaceutical love potion into your drink.

That’s the bad news. The not-so-bad news is that you may enjoy this potion if you took it knowingly with the right person. But the really good news, as I see it, is that we might reverse-engineer an anti-love potion, a vaccine preventing you from making an infatuated ass of yourself. Although this love vaccine isn’t mentioned in Dr. Young’s essay, when I raised the prospect he agreed it could also be in the offing. Could any discovery be more welcome? This is what humans have sought ever since Odysseus ordered his crew to tie him to the mast while sailing past the Sirens. Long before scientists identified neuroreceptors, long before Britney Spears’ quickie Vegas wedding or any of Larry King’s seven marriages, it was clear that love was a dangerous disease ... In his Nature essay, Dr. Young speculates that human love is set off by a “biochemical chain of events” that originally evolved in ancient brain circuits involving mother-child bonding, which is stimulated in mammals by the release of oxytocin during labor, delivery and nursing.

“Some of our sexuality has evolved to stimulate that same oxytocin system to create female-male bonds,” Dr. Young said, noting that sexual foreplay and intercourse stimulate the same parts of a woman’s body that are involved in giving birth and nursing. This hormonal hypothesis, which is by no means proven fact, would help explain a couple of differences between humans and less monogamous mammals: females’ desire to have sex even when they are not fertile, and males’ erotic fascination with breasts. More frequent sex and more attention to breasts, Dr. Young said, could help build long-term bonds through a “cocktail of ancient neuropeptides,” like the oxytocin released during foreplay or orgasm. Researchers have achieved similar results by squirting oxytocin into people’s nostrils — not terribly sexy, but it seems to enhance feelings of trust and empathy. Although Dr. Young is not concocting any love potions (he’s looking for drugs to improve the social skills of people with autism and schizophrenia), he said there could soon be drugs that increase people’s urge to fall in love.
