Aggressive behaviour is very rewarding from a cognitive perspective, with the brain interpreting it as a pleasurable activity on par with sex or recreational drugs, a new mouse study suggests.

"It is well known that dopamine is produced in response to rewarding stimuli such as food, sex and drugs of abuse," Maria Couppis, who conducted the study as her doctoral thesis at Vanderbilt University in Nashville, said in a release. "What we have now found is that it also serves as positive reinforcement for aggression."

Dopamine is a hormone-like substance that acts as neurotransmitter — translating the effects of things like drugs into sensations.

The study of mice involved placing a female and male mouse in a cage, with five other mice in a separate enclosure. In the course of the experiment, the female mouse would be removed from the cage and temporarily replaced with an "intruder" mouse. The aggressiveness of the male mouse was then observed.

Over time, the male mouse, trained to poke a target with its nose if it wanted the intruder to arrive again, increasingly signalled it wanted the other mouse to return and that it perceived the encounter as a reward.

When the male and female mice were given drugs that stopped the dopamine receptors in their brains, they stopped being so eager to have the intruder mouse return.

"We learned from these experiments that an individual will intentionally seek out an aggressive encounter solely because they experience a rewarding sensation from it," said Craig Kennedy, professor of special education and pediatrics at Vanderbilt.

"This shows for the first time that aggression, on its own, is motivating, and that the well-known positive reinforcer dopamine plays a critical role."

The study will be published online the week of Jan. 14 in the journal Psychopharmacology.

I think the trouble is that these states of aggression are only supposed to last for a short period of time.

If you walk around like that all the time it will exhaust you quickly.

I suppose so. I've told this story before, Narz, but maybe you didn't see it so I'll tell it again. As a kid I liked to fight. It seemed natural enough. Lasted right through 8th grade, then something happened, some kind of moral change and I quit getting in fights. Fast forward to my 40's, I'm splits with my wife and we're not living together. She's got some new guy who wants to marry her. I say fine, if you want a divorce let's do it. She gets cold feet and the guy is pissed. So one night, very late, he comes to my place, not far from his, and demands entrance. I tell him to go away but he keeps knocking loudly. So I figure OK I'll let him in and we'll talk about it. I'll tell him hey, it's up to her. Big mistake. He starts acting like a tweaker and won't leave. At this point my inhibitions against fighting are strong so I call the cops. The guys says he knows exactly what the cops are going to do when they eventually get there: they'll ask him a few questions to see if he should be taken to the County psyche ward. He'll answer in such a way that they'll send him home. Then he promised that he would return and do them same thing again. Well, the cops showed up and it went just as he said it would. The next day I was so furious that I got loose with some wine, walked to his place, punched him in the mouth, and went home to get arrested. They were going to charge me with felony assault because I broke one of his teeth, but the DA wouldn't touch it because of the prior police report from the night before. They sent it to some guy whose job it is to smooth these sorts of conflicts. He told me, well, so-and-so just wants an apology. I said I'm not giving it. He smiled and that was the end of it. The point of all this is that I felt a great joy in breaking that guy's tooth. It felt good. Aggression is very satisfying.

')For myself, I had to turn the other cheek quite a bit during my divorce. Just the decision to divorce was my way of avoiding the liability of the pent up frustration of both of us being stuck in an unacceptable situation. After I got custody, she keyed my new car and started stalking me, even after I got a restraining order. It was brutal. I learned a lot about anger management from that experience.

I used to beat up boys, who destroyed nests full of baby birds when I was 10, 11 and 12. I would do the same today, if I saw a man doing that, but this time I'd kick him in the crotch. Then when he was bent over, I'd give him a good chop to the back or a kick in the butt that would send him sprawling. Then I'd gently knee him in the kidneys. Just thinking about it makes me smile.

There's nobody on this forum I have ever wanted to punch.

There are people on this forum I've wanted to kiss!

I'll bet threadbear loved "Kill Bill."

Dopamine is the wanting and desire neurotransmitter, and for reinforceing effects of rewards. It is not necessarily the neurotransmitter for liking a reward. Why people with ADHD have less motivation and trouble completeing tasks.
