Scientists' Mouse Fight Club

An anonymous reader writes "To study how aggression, fighting, and winning change the brain, scientists set up a tournament of mice fights. They watched as the lab rodents took a break from their hum-drum existence and battled it out (however, the researchers broke the first rule of Fight Club by publishing a paper about their findings [abstract]). They found clear evidence of the 'winner effect,' in which a mouse that has just won a fight maintains elevated levels of testosterone and aggression, and is therefore more likely to win the next bout. Interestingly, the winner effect was strongest in mice that were fighting in their own cages — i.e., those that had home-field advantage."

      It wouldn't surprise me if it was perfectly legal to stage dog fights or cock fights in the name of science provided you do enough paperwork in advance. It's just the type of people who stage dog fights or cock fights are not the type that to do the paperwork.

    I know I'm not supposed to talk about it, but I once saw Mickey take on Mighty. Now, I put my money on Mighty. But, the bout was at Disney World. Mickey won in less than a minute. Then, all hopped up on testosterone, he basically took Jerry's head off in the next match.

    The article states the the effect is MOST pronounced when a mouse is defending its home territory. This means that they also had to study the effect when that motivation was absent. If you read the full text paper, and it will tell you more. It's behind a sign in page.

    Because the Romans weren't conducting a controlled scientific experiment? Because the Romans didn't write down their findings, nor were they attempting to answer a scientific question to begin with? Because what we know about gladiator fights is limited and uncertain?

  12. Re:Women... by Have+Brain+Will+Rent · · Score: 4, Insightful

    However there's no cause to single out genders/races/ages/etc. because such categories only go so far in explaining what are ultimately individual motivations.

    Since women appear to manifest aggression in very different ways than men (although increasingly exactly like men as an additional mode) it seems like a very worthwhile to single out the genders. For one thing female aggression largely goes unnoticed (or just plain denied) by society and consequently their victims are usually unnoticed as well.

    No kidding. In general when a man gets pissed at you, he lets you know, and maybe hits you or yells at you, but in the end you work it out. On the other hand when a typical woman gets pissed at you, you had better watch out. She probably won't tell you, and instead will use psychological methods to tear you apart from the inside in an attempt to completely ruin you and leave you a quivering shell of a man. Women are vicious. Men are so much easier to deal with because they bring problems out in the open. Most girls I have dated have said proudly that they think like guys, and don't act the way most women do (as I explained earlier). But guess what? They still do it, just not as often.

    In all seriousness, why is this modded as funny? Twenty percent of reported domestic abusers are female, despite the fact that a man is less likely to turn in his wife and that the police are less likely to take the case seriously due to cultural effects. Some studies have even shown that female on male spousal abuse is the more common form, though it is less physically damaging. Mothers abuse children more frequently than fathers, physical confrontations in schools are becoming increasingly perpetrated by females, and all of that says nothing to the more traditional forms of psychological and emotional aggressiveness practiced by many women.

    You're very right - the fact that it gets modded funny is tellingly symptomatic of the problem. Let's end the denial and take the blinders off for the sake of all. We could start by asking why the media (or the audience) considers it "funny" for a woman to kick a man in the genitals? Or just haul of and slap/punch him - with complete impunity. Even when it is clearly painful for the recipient it is somehow supposed to be funny. It's ok for women to lose control and hit - right? Because that is the message and very few people seem to see a problem with that.

    Well, that just sounds like sour dough to me. I don't see any way they could have performed this experiment any more ethically. I mean I don't want to seem rye, but understanding how mice brains work, which gives us a little knowledge of how our own brains work, is hugely valuable to humans and is worth a little cruelty (as little as necessary mind you).

    P.S. Have you tried it with falafel?
