On the Brain: 'Cuddle' hormone not always positive

This week we look at a brain chemical that can make you trust or suspect other people, the role of sleep in memory and other exciting new research and perspectives.

Rethinking oxytocin
You may have heard oxytocin described as the "cuddle hormone" because it's involved in the bond between romantic partners and between a mother and child. Studies have shown that it makes a person more trusting of others if he or she was already somewhat trusting. But now there's evidence that the chemical does not make everyone want to snuggle. New research finds that oxytocin can make someone who's suspicious of others even more hostile and uncooperative, reports ScienceNews.

Memory and sleep
Just knowing that you will have to recall something later makes you remember it better, a new study in the Journal of Neuroscience finds. The process of memory consolidation occurs during sleep, and it's common sense that if you don't sleep the night before a test, you won't perform as well as if you had. The study shows that it's not only facts that you remember better, but also learned skill sets, I reported for CNNHealth.com.

Kicking the habit
Will you quit smoking? A brain scan may be able to tell. Participants had functional magnetic imaging done of their brains while watching ads promoting smoking cessation. Researchers report in the journal Health Psychology that a reaction in the brain's prefrontal cortex was associated with reductions in smoking during a month after the brain scan. HealthDay via USA Today reports.

Scoring extra points with the kids
The mental health of young girls may benefit from playing video games with parents, Time's Healthland reports. The teens who played video games with a parent said they felt more closeness to their family and less aggression, and reported better behavior, than those who played alone or with friends. Researchers at Brigham Young University say it's the face-to-face time and interaction with parents that matters. It appears that boys did not display the same benefits, however.

'For fitter or fatter'
Marriage counselors are seeing more and more couples seeking therapy because of one spouse's athletic habits, which leave the other spouse feeling like an "exercise widow," the Wall Street Journal reports. Marathon trainings and other sporting excursions take away from family time, but are hard to give up. And sometimes getting buff attracts the attention of others, making the non-fit spouse feel insecure. The best solution is if both spouses engage in sports together, but it can still work out if one person just doesn't feel like it.

    I'm a personal trainer and have seen many married coupes have the 'For fitter or fatter' fight. One of them would be all exctied to get healthy and fit. The other wanted nothing to do with it. I found out as time went on the non-active spouse would try to sabotage the other. It was very sad an not very productive. Check out my health and fitness blog http://www.GrantStrong.com

      working on your own health is more of an individual sport. even if you go with friends...rare that your body would be doing the same thing at the same time...note bicyclists...always in different places. they can run together for a while, drafting and such, but carbs hit each person at different times.

      I lost a lot of weight and my husband was very supportive, yet did not sabotage me or exercise with me... once I started dropping weight and looking a lot better, he went & bought running shoes and started asking me which options were healthier when we went out to eat..
      I think that exercise and eating healthy are considered "bad words" in our society... (2/3 of us are obese or overweight). Sometimes, you DO have to go your own way and hope your partner will follow... It is terrible that a spouse would sabotage the other, but this is not always the case. Sometimes, we can learn from each other... which is what a healthy marriage is made of. :)

    I think that if your spouse expects you to give up something like marathon training or is less than supportive of healthy changes, you should probably leave. That just sounds like the hallmark of a horrible person.

      You would leave just like that, without even talking about it? It's not that cut and dry. Think about this: the spouse training for a marathon also has a full time job with frequent overtime. You realize one day that you haven't gone out for dinner once with your spouse in the past 3 months, the spouse has missed all of your kid's baseball games, and you two rarely talk or get intimate anymore because he/she is "too tired." If I was listed before marathon training on the priority list, I'd be pretty darn mad too.

      it would suck worse if they really had an undiagnosed allergy or infection (yeast, strep, etc) and it makes them tired. more likely an allergy (suspect corn...it's in everything). your body sends histamines...hard to breathe....makes you tired. no way to live. really. and we can't get these food companies to label the product. they are afraid we won't buy their product, but when we do...it makes us sick. its wrong and should be stopped.

    The big problem is when the non-athletic spouse is jealous of the athletic spouse and does her/his best to undermine the other's attempts to be fit. Of course, there are those people who are totally self-centered and do not care about anyone other than themselves, and those who are out exercising all the time to avoid a spouse they don't want to be with. I'm super-athletic, but my wife and kids always come first. My wife has asthma and cannot work out like I can, but I make sure she knows I love her just the way she is, because I do.

      Amen. I don't "work out" because of a health condition that's made worse by exercise. My fat lazy ex's excuse was that he'd only work out if I went with him, knowing that I physically could not do any exercise other than walk slowly, and he intentionally bought cheap uncomfortable shoes so he could refuse to walk more than a few yards because "my feet hurt".

      I have to agree with others posting here, your arrangement makes no sense. Why would you be so happy to settle for playing second fiddle to your husbands casual encounters with other men? It sounds like a unique arrangement, to say the least. Has it occurred to you that as a gay man, your husband is highly likely to find the love of his life that he wants to be with instead of a woman – meaning another man like himself. You sound like a masochist setting yourself up for betrayal. Then again, both myself and my husband are the "exclusive" types.

    There is a difference between overweight and fine with it, and overweight, complaining about it, but not doing anything about it. You should never break up with someone just due to their weight, but if they are unhappy with themselves, but too stubborn to make the effort to get what they want, that is a problem.

      Health care and food industry stand in the way of us being healthy. Don't be too quick to blame the victim in this case. Physicians aren't diagnosing/treating infections (yeast, strep, etc.) so they are unlikely to be able to deal with weight on their own. Infections will keep their blood sugar too high. Your body sends insulin to deal with excess blood sugar, and insulin loves to store fat and hates to let go of fat. VERY difficult to lose weight with infections. Also, a lot of people have undiagnosed allergies and that makes people tired. Often food related (corn is a big one and they put corn in everything...its hard to find food that doesn't make you sick ifyou are allergic to corn...that leads to chronic inflammation...over the long haul, probably damages small vessels. damage is done in the swelling and this just isn't where health care is at right now. its not in their training and they simply don't get it.)

      BadPatient The problem is being too addicted to TV and the computer and not eating well. I agree, marketing tactics trick people into eating food they think is "healthy." Just look at Subway, many of their "healthy" sandwiches have almost a day's worth of sodium. But if you have access to a computer, you can do research and learn how to cook healthy food and start an exercise plan.

      The majority of people are just too lazy to get off the couch. I understand being tired from working a full day, but come on! Get on a treadmill and just walk. Rent an exercise tape from the library if you don't have a treadmill or access to a gym. It's not hard to work out for 20 minutes per day, 4-5 times a week and to not shove fast food/chips/candy/etc into your face all day.

    If you are an able-bodied, shiftless couch-potato, have a spouse who assumes responsibility for his/her health/condition despite the challenges of adult life, attracts the admiration of others and feels good about him/herself, you have no business complaining about it or you need to get out of the way, plain and simple.

    I am not a big fan of running or marathon training which can cause health problems and I do think marathon work is extreme. There are plenty of less extreme sports such as hiking, swimming etc. Which couples can do together.

    I think if you are an exercise junkie and you marry a couch potato or vice versa, you either need to learn compromise, or you made a bad choice. Especially if they are going to want you to be different than how you are.

    The problem with the "I'm too tired to exercise" after a long day of work or whatever is that EXERCISING MAKES YOU MORE ENERGETIC. So it is a matter of willpower, and anyone who wants to be an apologist for people who waste away getting fatter is likewise a coward and an enabler. Get off your lazy fat butt and whip yourself into shape, there are NO EXCUSES.

    This had to be the result of a woman. A 'cuddle' hormone? Give me a break. Only a woman would offer such crap. And the 'for fitter or fatter' section proves it. Again, only a woman would complain about being an exercise widow, and read between the lines, '"just accept me for what I am" or "I am really beautiful on the inside". Women in the USA, what they need is to address their narcissism. It is always about what they WANT, to cuddle, the toilet seat, to be fat and not be responsible, gotta go I am nauceous.

      It's not "nauceous," it's "nauseous." But I think you mean to say "nauseated," which indicates a feeling the sensation of being queasy. "Nauseous" is an adjective referring to something that causes nausea. So coincidentally you DID use the correct word. Signed, a narcissistic know-it-all.
