When scientists — arguably the most logical of humans — try to make sense of love, interesting things are bound to happen. As Albert Einstein concluded: “Gravitation is not responsible for people falling in love.” (No one’s ruled out inertia, entropy, or nuclear fusion.) Traditionally, of course — metaphorically or otherwise — we trace the origin of love to our hearts. Thankfully, though, Syracuse University Professor Stephanie Ortigue suggests that our head has something to do with it, too — and not just when it’s over our heels.

In the new study “The Neuroimaging of Love,” Ortigue reveals that “12 areas of the brain work in tandem to release euphoria-inducing chemicals such as dopamine, oxytocin, adrenaline and vasopression.” Basically, “falling in love can elicit not only the same euphoric feeling as using cocaine, but also affects intellectual areas of the brain.” Apparently, when it comes to love, we can go from zero to sixty in 1/5th of a second — meaning that euphoria can enter our system as quickly, if not faster, than a controlled substance.

So falling in love is like being on cocaine. It happens real fast, you’re on this crazy high — and then you come down. Interestingly enough, cocaine was once an ingredient in Coca Cola. Coca Cola was first introduced as a patent medicine “for all that ails you.” Since cocaine isn’t legal and has long been removed from Coca Cola, maybe all we need is love?

Dr. Sean Mackey, chair of the pain management division of Stanford University, might agree. Writing recently in Time, Alice Park explores Mackey’s research into to what degree love might “influence how we experience physical pain.” Mackey discovered that when people who reported being in the first stages of “new and passionate love”  were shown pictures of their various pumpkins and pookies, they could withstand greater amounts of pain — even more so than when occupied by mental tests or when shown photos of equally attractive friends.

While I am all for love as a potential wonder-drug, one of my questions is: why only romantic love? Would throwing a different kind of love — say parent/child — into the pain equation garner the same results? Isn’t that love just as mind-altering? Nope, turns out. Well, not in the same way.

Ortigue’s study found that the reason parent-child love would likely not have the same effects on pain is that different parts of the brain are stimulated by different kinds of love: “Passionate love is sparked by the reward part of the brain, and also associative cognitive brain areas that have higher-order cognitive functions, such as body image.”

Parent-child love wouldn’t reduce pain physically because it doesn’t stimulate the reward center. However, that’s not to say that a parent wouldn’t be able to endure more pain should their child be in danger. In essence, Mackey’s study is strengthened by Ortigue’s assertion that the brain releases chemicals akin to cocaine to stimulate romantic love, because like cocaine, love works back and forth with the brain as it heightens certain things and dulls others. Love engages “our very deep, old and primitive reptilian system that involves basic needs, wants, and cravings.”

Since romantic love allows us to withstand more pain, perhaps it is the reason humans survive. While the end of love can hurt, to the point of making people lovesick, the euphoria of being in love keeps us coming back, much like cocaine keeps an addict coming back — all ensuring that we continue the species. From an evolutionary standpoint, the emergence of romantic love in humans may be all about survival of the fittest – rewarding us for the formation of potentially strong alliances with our mates and, as shown by Mackey allowing us to withstand greater amounts of pain, which from a primitive standpoint would have been useful in a fight with that mastodon.

Be thankful. Biology is looking out for us in more ways than one.

Falling in love is kinda like coming down with a fever: it creeps up on you, makes the cheeks run red, and the best remedy for it is to spend lots and lots of time in bed (hummina hummina). Then the fever breaks. In fact, for a long time running scientific wisdom has been that the fever might run its course in a mere year; after that, it’s dunk yourself in an ice bath, get a pacemaker to calm those heart flutters, and settle into a more platonic, less charged life with lovey.

Now a new study suggests that for a lucky few, that bloodsugarsexmagik passion is more akin to a really, really fortunate case of herpes for which there is no cure.

“Brain scans have proved that a small number of couples can respond with as much passion after 20 years as most people exhibit only in the first flush of love. The findings overturn the conventional view that love and sexual desire peak at the start of a relationship and then decline as the years pass.”

Only about 10 percent of the couples studied were found to pump equal amounts of dopamine through their systems when shown a pic of their betrothed as they did a couple decades prior. The researchers dubbed these couples “swans” because swans mate for life, but I mean, gag me.

No word from the study on the why and how of all this, but this primer on how to pucker might prove helpful.

Having once seriously dated a fantastic, and fantastically ugly, guy, I have developed the following fugly-guy philosophy: You have to feel in your lusty places that your man is, like, the hottest guy in the world. In your head, however, you may acknowledge that he is perhaps the hottest guy in the world only according to you.

A recent study about the relative physical attractiveness of spouses seems, at first glance, to bolster my theory, stating that hot-wife/not-so-hot hubby couples often feature the most mutual encouragement and support.

For those of you in a re-relationship like mine, it turns out we are not the freaks our friends try to make us out to be. In fact there’s an entire subset of relationships — with their own TV role models, of course — that have risen from the very ashes of their own breakups. (Again, and again, and again.)

According to a recent article in the Contra Costa Times, the cycle of breaking up and making up with the same person — you know, in the inimitable words of Charlene: “That man you fought with this morning, the same one you’re going to make love to tonight” — has a lot to do with our biological makeup, our fears of being alone, and, in some “extreme” cases, an addiction to the “I love, I mean hate, I mean LOVE you” drama.

Lisa Gray, a marriage and family therapist, says: “[These couples] get addicted to that up and down of emotion. The more quiet, stable love is not really cultivated as something to be respected. Just watch the common TV shows. These loud breakups-and-get-back-togethers are what get the attention.”

If that’s the case, I, for one, would be perfectly happy to spend the rest of my life never getting any attention ever again. Quiet, stable love, where are you?
