Dirty Minds: 5 Sex Myths Bashed By Brain Science

Posted: 01/19/12 08:19 AM ET

We've heard it time and time again: there are "rules" when it comes to love. You have to act this way (never that way) to attract love. You have to represent your gender-specific planet if you want to nurture and keep it. And you can--no, you must--change up some of your natural inclinations if you want to find any semblance of happiness in your relationship. We hold hard and fast to a lot of ideas when it comes to love and sexual behaviors. But does science actually back them up?

Neuroscience, the study of brains and behavior, is offering us a new lens to view love, sex and parenting. And, as I learned while researching "Dirty Minds: How Our Brains Influence Love, Sex and Relationships" [Free Press, $25.00], these new and exciting brain studies are blowing some commonly held ideas about relationships right out of the water.

Love is an emotion.

In my son's kindergarten class, love is classified in the same category as anger, sadness and surprise. They call it an emotion--as do many poets, authors and boy bands. But anyone who has ever been in love knows it's not quite as fleeting as the other items in that emotion group. And neuroscientists have uncovered neuroimaging evidence that suggests love is more of a drive--not unlike our drive for food, drink and sex.

Helen Fisher, an evolutionary biologist who studies love at Rutgers University, recognized that romantic love is a very powerful physical experience. Think about it: your heart may race, your palms may sweat and you may find yourself feeling a little obsessive. And when Fisher found a distinct system in the brain for romantic love, separate from nearby systems implicated in sex and attachment respectively, she concluded that romantic love is a drive there to not only help fuel reproduction but to also help us connect with others. Simply put, romantic love is not just a "nice to have"--it's evolutionary drive. Time to change the kindergarten emotion chart!

Men want sex, women want relationships.

This story is as old as time--we're told from day one that men and women want different things from their co-mingling. Namely, men only want the booty while women want something deep, meaningful and long-term. Despite plenty of anecdotal evidence to discount this notion, we still cling to it. Yet, brain science suggests that there is a lot more variability within one sex than between the two sexes when it comes to relationship behaviors. Not only that, but there is no difference in romantic love's brain signature (that is, the type and areas of brain activity seen when people look at photos of their beloveds) in men and women. Pair those studies with epidemiological and survey data that show that men and women have the exact same reasons for having sex and it's time to rethink this stereotype.

Love and hate are polar opposites.

Going back to that kindergarten emotion chart, love and hate are thought to be polar opposites. They certainly feel that way! But Semir Zeki, one of the pioneers in the love neuroimaging space, decided to see whether he could find a hate signature in the brain. He did--and while he saw some unique brain circuitry light up, he also demonstrated that love and hate share some key brain areas. Zeki admits that the result may be due to the fact that many of his study participants directed their hate toward a past romantic partner--but the old cliché about there being a thin line between love and hate may just be backed up by our brain activity.

Porn appeals only to men.

Our brains, it would seem, are hard-wired for porn. Thomas James, a neuroscientist at Indiana University's Kinsey Institute, says that sexual stimuli create a brain response 2-3 times stronger than any other kind of image he's ever used. This phenomenon is not limited to men. Women's brains also light up like Christmas trees when they check out images that are sexual in nature. Researchers at the Kinsey Institute found that men and women showed some differences in brain activation when they looked at sexual images which led Heather Rupp, the lead researcher on the study, to say that arousal circuitry may be differentially activated in men and women depending on the images. Despite this, however, both sexes rated the images used as equally arousing and looked at them for approximately the same amount of time--suggesting that women also have some appreciation for visual sexual stimuli.

Men are genetically programmed to cheat

If only it were that easy--I'm sure a lot of guilty people would sleep easier tonight! Alas, it's not.

First off, if men were genetically "programmed" to cheat, we wouldn't see as many women skipping out on their partners. But even if we could ignore that little fact, genes are not little generals directing our sexual and mating behaviors. Genes can certainly predispose us to certain behaviors--but ultimately, our large, evolved frontal lobes (implicated in judgment, decision making and empathy) allow us to make a choice, even when temptation seems just too compelling to ignore.

That's true. And there are a lot of misconceptions everywhere about how the world is going on.
This is what i call the difference between the real (objective facts about the world) and the reality (subjective representation of the world) we all have.

More these two views are far from each other more the decisions we make are willing to be wrong decisions and more we have to bear consequences of wrong choices.

Love is a concept which has evolved during history of humanity. It is also what i call a luggage word: everybody puts what he wants in it. Usually love is more attachment which often leads to pain.

m/33...it is NOT bred in all men to cheat. it is a choice. its simple, treat your man well. with me, good treatment breeds loyalty, he mentioned guilt...why would we feel guilty if we are not being treated well? have i ever cheated? the answer is not on the women who did me right. most men will NOT admit this...but when we arre done right, we are proud of our partners like women are of "their man"...and will be faithful. i can be a faithful man or a DOG...its the woman and how she treats me that decides which kind of partner i am.

well said. I agree.

You'd think you'd have enough self-respect to just not be a cheater ever. Your dignity should not be contingent on someone else's actions.
05:16 PM on 01/26/2012
i highly disagree. first you dont know me or my situations to make judgments. i was faithful for 12 solid years to a good woman until we split, i never touched another soul. when i HAVE cheated? it has been on women online who i have met once or twice in person, women who i usually caught being shady or just vanish for months at a time. i stand by my actions, it takes two to make it work, not just me doing all the work. do your part and ill do mine. if you are not around for 3 months and do not even have the decency to send an email, and someone ELSE gets my time, whos fault is that? my dignity is intact knowing i am good to every partner unless they start screwing me over. it does not take dignity not to cheat when you are being done wrong, it takes stupidity.

I think this is one stepping stone,
like sigmund freud's Ideas about Women wanting a penis.
that may have been valid at the time,maybe not so much anymore.
I think as time, and medicine progress,we will find this is nt as simple as this makes it sound.

I find the women always cheat before the men do. Most of the black women have to have a male harem to feel good about themselves.

I had some of the first video stores in CA. in the early 80's. I had a x-rated section in each store. We kept a running record of all videos that were rented by the video name and the customer name. Our x-rated movies were rented to more women then men. I can only imagine what that market must be now with the ease of the internet.
01:59 AM on 01/23/2012
Our family had a chain in New Jersey (through the 90's) for some years and it was the exact opposite, I'd say about 95% male renters. (from our adult section) Very interesting how the demographics play out depending on where the store is located in the country.

I don't believe that is proof positive enough. I mean women have rented porn because their boyfriend's suggestion and men buy tampons for their women, etc.

Cheat is a position only if you include monogamy. I personally find it to be fulfilling (maybe I'm lucky) but biologically I'm reminded of "The King and I". "Woman is like a flower, with honey for just one man. Man is like a honeybee, must gather all he can." Perhaps a backhand reference to the primate mammal troups where one male is in thrall to several or many females. Ah, but while community property reigns in civilization, a man must hold himself true to his prosperity, if not to his biology.

Many honeybees land and take from a single flower.

Comparison of the human to the wildlife world in this context is unrealistic because of our ability to populate so vastly and are at the top of the food chain. If our population were to decline to significantly under a billion people, monogamy might then become obsolete to ensure that our species doesn't become extinct.

Fear, a lack of confidence, but mainly fear.

I agree with the one "love is the polar opposite of hate" in my opinion, hate isn't the opposite of love, indifference is. If you think of it, love and hate are both very powerful heated feelings. I find hate to be just as addictive as love can be if you let it get to you. I know I am completely over someone when I no longer care who they are dating, where they are going etc. If Im spending my time reacting, even with a negative feeling, it seems to mean there are other emotions going on as well.
02:43 AM on 02/04/2012
Indifference may imply that there is not the same brain activity as is generated by love or hate. I'm of the opinion that there is a fine line between love and hate, as shown in brain studies. If you've ever been married and divorced, you may have noticed that the person, whom you loved, may have turned into someone who did not want what was best for you or the marriage, but for him/herself. My ex was filled with, what appeared to be hatred, at the end of the marriage.
06:40 PM on 01/22/2012
love is wanting what is best for a person dispite what we want
02:45 AM on 02/04/2012
That's a tricky one. Who determines what is best for that other person in the relationship? What if you vehemently disagree with what the person thinks is best for her/him?
10:41 PM on 02/04/2012
i did and let her go. common sense will tell what is best for them. love is NOT forcing your opinion on a person.

In the beginning before sin, didnt God give Adam one women/ , so this "Myth that men were made to cheat, is just that , and has been a terrible exuse for cheating , it's a form of self centernedness and disrespect
05:53 PM on 01/22/2012
No. It's 200,000 years of ensuring the species continues. By comparison, one man and one woman in marriage is only a couple of thousand years old. You do the math. Marriage is a woman's form of self centerdness.
01:08 AM on 01/23/2012
Your theory only works if you believe in evolution and not creation. If you believe in evolution
then you believe the world is millions of years old. However, under the belief of a creator--
God, the world is only a few thousand years old. As your 2nd sentence suggests. mvette76
is correct.

Not really...as we evolved...the males had to protect their off spring and thus had "parental duties" which meant that they had to stay with their mate. There actually are animals that mate for life, believe it or not and one can always argue that marriage/monogamy is the man's way of being self centered because he is ensuring the female only has his off spring.
05:08 PM on 01/22/2012
i see only two emotions.... love and fear. we know what love is. fear begets hate, anger mostly becouse of insecurity. it causes possessiveness.. there have been cases where a man will control his woman with financial insecurity, physical restraint and theats of violence all based on fear. jails are full of men like that. and some women that lilleed their husbands out of fear. love is when you place your partner first and foremost. folks remained married to eachother for life thats love.
10:10 PM on 01/23/2012
Love is not enough to hold a marriage together for life.
05:13 PM on 01/26/2012
yeah takes more than that, i'll buy that. ever see some one that gives of themselves to be couteous, kind, gentle, smile, hold doors open for an elderly person. they are the ones with love in their heart. love must be a factor in a relationship to last.
02:55 AM on 02/04/2012
I disagree. With real love comes commitment, compassion, empathy, caring, supportiveness, selflessness, valuing and cherishing the spouse, nurturing, expressing, connection, comfort, collaboration, resolution, and the list goes on. What is missing that you claim that love is not enough?
