Sex Boosts Brain Growth

CmdrTaco posted about 4 years ago | from the do-it-for-my-brain-baby dept.

Science 251

climenole writes "Sex apparently can help the brain grow, according to new findings in rats. Sexually active rodents also seemed less anxious than virgins, Princeton scientists discovered. Past findings had shown that stressful, unpleasant events could stifle brain cell growth in adults. To see if pleasant albeit stressful experiences could have the opposite effect, researchers studied the effects of sex in rats."

Stressed and axious people are not the typical types that lead. Leaders are more atractive because they are garanteed to protect others from dying in certain dangerous situations.

Evolution theory, bitches.

That doesn't mean that your typical athlete would ever outgrow the brains of who is too stressed to let his/her brain grow that fast.

BTW orgasms where good for about ten thousand brain cells, right? How much brain cells do you think you loose when you bang a soccerball with your head? About the same.

Just because they chose to focus on physical mastery over themselves, then managed to get a sweet gig making millions of dollars doing something fun doesn't make them "morons." Hell, if I could make a mint playing games all day, why would I bother looking for the Higgs Boson?

Besides, consider the following: The major goal in any living being's life is to ensure the survival of his genes. Those who get the most action have the best chance of doing so, which means on a sub-conscious, primal level they're going to have less to worry about. That means they won't be distracted from focusing on what's important to them.

If more nerds got some, maybe we'd have the Higgs Boson on lock already.

Re:Bullshit (1)

Pharmboy (216950) | about 4 years ago | (#33111810)

I think you have to consider the whole picture here: How many people in high school go to college vs. how many make a good living 10 years later? A pretty good percentage. Now, how many people in high school decide they want to be a basketball playing millionaire, and what percentage make it? Inversely, what percentage of each of those groups are now living below the poverty level?

I would venture a guess that there are more millionaires that went to business school than who played professional sports of any kind, so while your comparison is interesting, it isn't really a good analog.

Re:Bullshit (2, Interesting)

bsDaemon (87307) | about 4 years ago | (#33112008)

Yes, but let's look at business school types. Your typical MBA probably at least was on a crew team in high school or college. Lacrosse is a good substitute, too. Their undergrad major was probably in a subject where there were lots of girls, so they had more opportunity to get to know women and how to interact with them, thus more chances for breeding.

They then went on to get an MBA, bought a new BMW 'cause the one their dad gave them for their 16th birthday was showing its age, and probably kept on playing squash or basketball at the Harvard Club with their alumni friends. So, now they're in shape and have shiny things to use as bait to attract a mate (the BMW).

The professional athletes skip the MBA step and go straight to the fancy cars and lots of money.

-----

But, back to the text of the article itself, it indicates:
1) that males who merely interacted with females on a more regular basis were less nervous in general than the ones who only got to see a female every 2 weeks.
2) the ones who were sexually active were less risk-adverse, such as more willing to eat food in strange places.

compare this to humans:
1) your typical nerd male who spends all his time in a lab or on a computer and doesn't get out much, doesn't really know what is and is not ok to say to girls in the rare instances where its required to interact with one outside of the context of a checkout clerk at the convenience store.
2) your typical nerd male is going to be harder to talk into doing risky behavior such as hang gliding or whatever, because he'll be too busy worrying about the elevated risk of death, subconsciously due to the fact that he more than likely hasn't reproduced yet, and therefor would lose evolution.

So, the immediate lesson from the study basically boils down to if you have more experience around the opposite sex you're not going to freak out and be awkward, and if you've already passed on your genes then it really doesn't matter what happens to you, from an evolutionary standpoint. The MBA works just as well as the pro athlete.

Besides, if I just wanted to be a dick about it, I could always just pull out Brian May, the guitarist for Queen, who recently finished a PhD in astrophysics from Imperial College in London. That's a good counter-argument to the original poster's Bon Jovi jab.

I have to disagree with you on a couple of levels. First, I am a glider pilot (hang gliders), and a high majority of the 100+ members in my club are engineers or technologists of some sort. The skill and depth of knowledge required are very appealing to this type of person.

Having participated in team sports and more "extreme" sports myself, you run into a lot more of the nerdy/dorky type in these areas.

Re:Bullshit (1)

bsDaemon (87307) | about 4 years ago | (#33112606)

I just picked hang gliding as an example at random. Having been a small plane pilot myself, there is definitely a draw to various forms of powered and un-powered aviation to more technically inclined people. Perhaps I should have used bungee jumping or something instead. However, I still think there is a much higher degree of risk aversion among nerds (not necessarily technical people -- after all, most of the original astronauts had engineering degrees and were military test pilots -- but, you know... the mountain dew moustache and cheetos-fingered d&d tshirt wearing nerd)

"1) that males who merely interacted with females on a more regular basis were less nervous in general than the ones who only got to see a female every 2 weeks."

I have noticed that since I switched watching random TV for an hour a day, for watching certain sorts of camgirls, my anxiety has gone way down.

Namely - not solely the ones that are simply girls wiggling for tips, but ones where the atmosphere is more like a moderately active IRC channel, just with a (sometimes) naked girl as one participant, interacting with the others on a wide range of topics.

Sure - interaction in person would be better, and probably more healthy.

That's funny. I couldn't give a rat's ass if my genes get passed on. However, I do enjoy having a partner for the companionship and love it brings. There's more than one reason to pair up with someone you love; passing on your genes is only one of them.

I get a lot more out of a few hours snuggling in the dark talking with someone I care about than a quick session of mindless sex with someone I just met. Does this make me strange, or does it prove that "passing your genes on" isn't the only factor here? I'd say the latter.

Although I AM pretty strange sometimes. But that has less to do with sex and more to do with normal being boring. ;)

That means they won't be distracted from focusing on what's important to them.

If we want to get all pseudo-psychological (not saying you are, just disclaiming that I have no idea what I'm talking about), then I would wager that the animals who are getting tail in truckloads aren't striving for survival, they're trying to prove that their masculinity is intact and working well.

As opposed to another animal who only mates a couple of times and hits a home run ("She's pregnant! GO HOME, RUN!"), they can go to bed knowing that their lineage's survival is safe.

I'm not saying that the average /. stereotype doesn't get tail because he chooses not to; my train of thoughts goes more into a direction that as cultures get more civilised, their tendency to have 5 or more children slopes down very quickly.

So, as the GP said, a person with a decent education will have less of a need to get tail, as they will be able to focus on different things -- one might even say "more important" or "higher level" things. A monogamous relationship, almost symbiotic, making conscious decisions about when to have children, how many, and how it will fit into the household and careers of the involved parties; as opposed to the bulging sack of muscle emptying his backup singers on every cute face that opens her mouth and having sub-conscious, primal level instinct "hope" for offspring.

Brain growth doesn't necessarily equal greater book-smarts. /. probably is full of social retards, i.e. anxious, geeky, less-confident "nerdy" types. And trauma or prolonged "unpleasant stress" situations can certainly affect a person's thinking. Just cause it's all in your head doesn't mean it isn't really happening on some physical level. The brain adapts as it grows to the different ways it's forced to function, like any other living thing.

Aside from the funny part, that is closer to the truth than you like.

Most of our current mainstream religions, i.e. the monotheistic, abrahamic ones, basically need you to feel horrible because their story says the world is bad and the afterlife can be good if (and only if) you follow their teachings.

It's hard to feel like shit after a good night with a lover. Your desire for spiritual salvation is quite a bit low after a hot threesome. Your belief that this world is all bad and evil and only the afterlife counts is kind of weak in the middle of getting your brains fucked out.

Rene S. Hollan (1943) | about 4 years ago | (#33112004)

I know men who had good jobs, paid their share of child support, became unemployed and even when they managed to get reemployed, would up living almost under a bridge: child support is assessed on what you "can" earn, not on what you do, and, unlike the stock market, past performance IS indicative of future obligations.

Contraception is never perfect (even sterilization), having MORE kids can land one in jail (for neglecting the kids one has by taking on additional obligations, thus depriving them), and in the industrialized world, children are a HUGE financial liability and risk. Further, we already have WAY too many people for this planet to support.

Further, there is evidence that early sexual activity is inversely related to intelligence, though the initial study that alleges this is racially prejudiced, and statistically flawed: it placed asians at the top of the hierarchy, followed by whites, followed by blacks and everyone else. IIRC, the standard deviation of the error wiped out any statistical significance. Still, we all remember the "smart asian kid" in school who got straight A's and never any "action"/
 

Re:Clearly, these rats don't pay child support. (2, Insightful)

MaWeiTao (908546) | about 4 years ago | (#33112252)

I think academic performance comes down to upbringing, not race. Although races might place different levels of importance on some things. The asian kid got straight As and never saw action because his parents demanded he excel in school and didn't allow him to socialize. Once you socialize too much grades inevitably suffer. Asians are no smarter than anyone else. Live in Asia for a while and you'll be cured of that misconception. It's like foreign kids who excel in college. They do well because they specifically came to the US to study and are appreciative of the opportunity.

Americans, on the other hand, don't appreciate what they have and are in school to study. And worse, in certain communities positive role models and discipline are seriously lacking. And there's too much of an anti-establishment attitude. The ability is there, it's just totally wasted. I'd say sexual activity is more of symptom than a cause.

Sex Boosts Brain Growth... in rats.

Lets not forget the last part of the sentence.

elaine stops having sex with her boyfriend to motivate him to pass an exam (another commentary on sex and smarts) and george stops having sex because his girlfriend has mononucleosis. george gets progressively smarter (until he spontaneously learns portuguese and therefore seduces a portuguese woman, thus becoming a stupid again), and elaine gets progressively dumber. some humor from jerry's summary of what's going on in their heads:

to george:

George: What is Tungsten or Wolfram?

Alex Trebek: We were looking for 'What is Tungsten, or Wolfram'.

Jerry: Is this a repeat?

George: No, no, no. Just lately, I've been thinking a lot clearer. Like this afternoon, (To television) what is chicken Kiev, (Back to Jerry) I really enjoyed watching a documentary with Louise.

Jerry: Louise! That's what's doin' it. You're no longer pre-occupied with sex, so your mind is able to focus.

George: You think?

Jerry: Yeah. I mean, let's say this is your brain. (Holds lettuce head) Okay, from what I know about you, your brain consists of two parts: the intellect, represented here (Pulls off tiny piece of lettuce), and the part obsessed with sex. (Shows large piece) Now granted, you have extracted an astonishing amount from this little scrap. But with no-sex-Louise, this previously useless lump, is now functioning for the first time in its existence. (Eats tiny piece of lettuce)

George: Oh my God. I just remembered where I left my retainer in second grade. I'll see ya. (He throws finished Rubik's cube to Jerry and he exits. Kramer enters)

to elaine:

Elaine: How come he's gettin' so smart? I stopped having sex with Ben three days ago and I don't know no Portuguese?

Jerry: Are you all right?

Elaine: I don't know. It's just the last coupla days my mind has been, not good.

Jerry: Wait a second, I know what's happening. The no sex thing is having a reverse effect on you.

Elaine: What? What are you talking about?

Jerry: To a woman, sex is like the garbage man. You just take for granted the fact that any time you put some trash out on the street, a guy in a jumpsuit's gonna come along and pick it up. But now, it's like a garbage strike. The bags are piling up in your head. The sidewalk is blocked. Nothing's getting through. You're stupid.

Elaine: I don't understand.

Jerry: Exactly.

Pleasant albeit stressful? (1)

DaTroof (678806) | about 4 years ago | (#33112102)

To see if pleasant albeit stressful experiences could have the opposite effect, researchers studied the effects of sex in rats.

Are these rats into extreme bondage or something? "Pleasant albeit stressful" is how I might describe a satisfying occupation, not a satisfying sex life.

Celibacy and creativity (1)

topcoder (1662257) | about 4 years ago | (#33112132)

There is a well known rumor that keeping celibacy is a great source of creativity.

From Nikola Tesla's webpage:

"Tesla never married. He was celibate and claimed that his chastity was very helpful to his scientific abilities.[22] Nonetheless there have been numerous accounts of women vying for Tesla's affection, even some madly in love with him. Tesla, though polite, behaved rather ambivalently to these women in the romantic sense."

I am sure i could find some other intellectuals who were celibates, or at least didn't give so much importance to sex. Maybe the greats insights of these genius provided them with greater pleasure (and less ephemeral) as substitute for physical orgasms. Or it may be simply that they didn't have much time or didn't give the importance to it.

They got it backwards... (1)

It's not that sex helps the brain grow, it's that sex helps prevent stress, which has been found to cause the brain to shrink.

No longer will a guy have to resort to tactics like:
"Hey, baby, I'm shipping off to Iraq tomorrow, and I'm not sure if I'll make it back. Can we spend this one night together?"

Instead, it'll be:
"Hey, baby, I'm taking the SAT tomorrow, and I'm not sure my score will be good enough to get into Stanford. Can we spend this one night together?"

Well, it sure works for me ... (1)

If having sex all the time made people smart, your mom would be brilliant.

As it is, she thinks the Linux kernel is something you pop in a microwave.

Does exercise work? (1)

MaWeiTao (908546) | about 4 years ago | (#33112432)

I'm not clear on what is meant by pleasant but stressful experiences. Do they mean physically or emotionally stressful. According to the article the rats which have had sex are less stressful. So where does the stress come in? Were they stressful beforehand and sex simply alleviated that?

But then if it's a stressful but pleasant activity that causes brain growth then that would imply any pleasing activity should produce the same result. Playing video games, sports, mountain climbing, etc should all be able to produce the same results. Presumably masturbation would work too.

It sounds to me like they're stating the obvious. You'll feel better if you do something enjoyable.

Now if we could only get a headline like "brains boost sex growth" then we'd be in business. Somehow if that were the case, I think high school would have been a very different experience for most of us.

This is all part of an elaborate scheme to get the cute new lab assistant to sleep with the head researcher. A little open and honest communication would have saved a lot of funding.
