Love on the Brain

Scientists peeking inside our brains and psyches have more clues than ever about the biology of love -- why we're attracted, why we fall so hard, and what makes us stay.

Kissing: The Hot Love Habit That Makes You Both Happier

By Ayana Byrd   Have you ever wondered why we kiss? It's actually a strange way to spend your time  lips smooshed together, breath (good or bad) mingling, and let's not even get into the tongue action. Yet we love it. We cheer when movie characters seal their happily-ever-afters with a smooch. A bodies-pressed-together kiss can make you remember why you adore the man who was annoying you just a minute ago. Why is that? "For some women, kissing is even more intimate than intercourse," says...

Before you say "not a chance," hear another view.

It's probably a good match, says Helen Fisher, PhD, a cultural anthropologist from Rutgers University and a leading researcher on love, attraction, and romance. One of her findings: Biology matters, and these two people's biology -- their chemical "profiles" -- may complement each other nicely.

In recent years, Fisher and a host of other researchers have been looking deep into our psyche and brains -- helped by high-tech imaging and genetic analysis. They've come up with some intriguing information about what makes us become attracted to someone, what underlies the crazy-in-love feeling, what's up with the transition from butterflies to a more comfortable relationship, and what keeps us attracted.

"It's all much less of a mystery than it was five years ago and certainly 30 years ago," says Arthur Aron, PhD, a professor of psychology at the State University of New York at Stony Brook and another top researcher in the field. The science of the biology of love is relatively new. Research picked up steam in the 1980s, Aron says, and since then experts have made multiple discoveries. Here's a sampling of their findings:

The Biology of Love: Biology Matters

When it comes to whom you are attracted to, "your biology plays a role,'' says Fisher, who wrote Why We Love and several other books. It's not only a similar socioeconomic status, level of education and family backgrounds that make people attractive to you, she says, but also hormones -- ones that differ from your own.

We're attracted, Fisher says, to those with a chemical "profile" for estrogen, testosterone, dopamine, and serotonin that's different from our own, yet complements it. For instance, she says, "If you tend to be high estrogen, you will gravitate to the high testosterone type.''

That explains why Mr. Analytical and Driven and Ms. Gregarious and Warm are a match. He's probably a ''high testosterone'' type, Fisher says, and she is probably a "high estrogen" type. "For good Darwinian reasons, they are very complementary," says Fisher. She can likely see many ways of doing things and become indecisive. To the rescue, the analytical man. Likewise, she might inspire more compassion in him. Fisher is working with chemistry.com, an offshoot of match.com, to develop this chemical profile match strategy.
