"New research on mice shows the brain processes aggressive behavior as it does other rewards. Mice sought violence, in fact, picking fights for no apparent reason other than the rewarding feeling. The mouse brain is thought to be analogous to the human brain in this study, which could shed light on our fascination with brutal sports as well as our own penchant for the classic bar brawl. In fact, the researcher say, humans seem to crave violence just like they do sex, food or drugs.

Scientists have known that mice and other animals are drawn to fights. Until now, they didn't know how the brain was involved. The new study, detailed online this week in the journal 'Psychopharmacology', reveals the same clusters of brain cells involved in other rewards are also behind the craving for violence. "Aggression occurs among virtually all vertebrates and is necessary to get and keep important resources such as mates, territory and food," said study team member Craig Kennedy, professor of special education and pediatrics at Vanderbilt University in Tennessee. "We have found that the reward pathway in the brain becomes engaged in response to an aggressive event and that dopamine is involved."

For the experiments, the researchers placed a pair of mice, one male and one female, in a cage. Then, the female was removed and a so-called male intruder mouse entered the cage. That triggered aggressive behavior in the resident male. The tell-tale signs of aggression included tail rattle, an aggressive sideways stance, boxing and biting. After the initial scuffle ended, the resident male mouse was trained to nose-poke a target to get the intruder to return. Results showed the home mouse consistently poked the target and fought with the introduced mouse, indicating, the researchers say, that the aggressive encounter was seen as a reward. "We learned from these experiments that an individual will intentionally seek out an aggressive encounter solely because they experience a rewarding sensation from it," Kennedy said.

To figure out whether the brain's reward pathway was involved, the scientists treated the home mice with a drug to block dopamine in certain parts of the brain known to be involved in rewards like food and drugs. The treated mice were less likely to instigate the intruder's entry. “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," Kennedy said. Kennedy explained that the experiments have implications for humans. The reward pathway in the brains of humans and mice are very similar, he said. "Aggression is highly conserved in vertebrates in general and particularly in mammals," Kennedy told LiveScience. "Almost all mammals are aggressive in some way or another." He added, "It serves a really useful evolutionary role probably, which is you defend territory; you defend your mate; if you're a female, you defend your offspring." Even though it served a purpose for other animals, in modern human societies, Kennedy said, a propensity toward aggression is not beneficial and can be a problem."

So what's new. I wonder how much this research cost taxpayers?

Actually, wars are caused by the equator.

The closer that you get to the equator, the more wars there have been throughout history.

When was the last time Alaska and Siberia fought a war?

When was the last time Canada and Greenland fought a war?

When was the last time Alaska and Siberia fought a war?

When was the last time Canada and Greenland fought a war?

985 AD Greenland's Vikings attempted a settlement on the North American Continent (Vinland) and had immediate conflict with the natives (Skraelings):

Bloody First Contact — When Vikings Clashed with Natives in the New World

“Almost as soon as the Norsemen hauled their long boats onto the beaches, fighting broke out with the local natives.”

MANY POINT TO the Jamestown Massacre of 1622 as the first clash between European settlers and native North Americans.

A harbinger of centuries of bloodshed yet to come, the incident saw a body of unarmed Powhatan warriors infiltrate the wooden palisade of England’s struggling Virginia colony only to launch a pre-meditated surprise attack on the settlers using what tools and weapons the raiders could lay their hands on. Nearly 350 colonists were killed in the ensuing battle.

And while the attack ushered in 300 years of almost ceaseless violence between the white settlers and natives, it wasn’t the first occasion in which Europeans met North American aboriginals on the battlefield. More than five centuries prior to Columbus’ voyage of discovery, a party of Vikings under the leadership of Thorvald Eiriksson established small a colony in modern day Newfoundland.

Thorvald, the son of Erik the Red and brother of Lief Eiriksson, landed in the New World sometime around 985 CE. The 50-member party eventually set up a fortified camp on the large island. Yet almost as soon as the Norsemen hauled their long boats onto the beaches, fighting broke out with the local natives.

In an early encounter, Eiriksson himself was struck by an arrow. His injuries would prove fatal.

“I have been wounded under my arm. An arrow flew between the edge of the ship and the shield into my armpit. Here is the arrow, and this wound will cause my death,” one contemporary account records the Viking leader as saying. Eight natives were also killed in the engagement.

The small band of Europeans continued to fight the local population for the duration of their stay. The Vikings dubbed their enemies Skraelings, which means either “barbarian” or “foreigner” in the old Norse tongue. It could have also meant “weak” or “sickly” or even “false friend”. [2] The inhabitants were most likely Inuit.

Maybe it's not violence we crave but the adrenaline rush? Just asking, since I think that's why I use to do crazy dangerous things. Or it might be that I was just crazy.

I think you are right about the Adrenaline Junkie theory. It is widespread, Look at how many "extreme" sports are televised reguarly as well as the rage for Parquor and Free running. Most of those people have broken many bones in their pursuit of risky moves.

How many times have you seen the scenario when mountain climbers attack a peak knowing that bad weather is socking in and they have to be rescued? Then some other adrenaline junkie risks his life in flying a helicopter into a shoebox on the side of a mountain with gale force winds whipping him around. No one ever says "pack of dumb asses got what they deserve, let them freeze".

Well, what better way to go... than laying down your life for your fellow man. There is a missing sub down Argentina way... they found it today and their oxygen is suppose to run out today... somebody is going down there to save them today... rough seas and all... what a rush.

Can’t you just see the defense of a person involved in any criminal act saying “ my dopamine was out of balance, I didn’t even know what I was doing..”

I have read similar suggestions of aggression being motivated by inferiority and causing their mind to release more hormones” inciting the bodily aggression..

For me, I mediate releasing my inner hostility of the day.. mind over matter and when finished it just doesn’t matter anymore..🌹

Happy Thanksgiving to you and your delightful family...

Significant difference, those were military people in that sub, they were in harms way, in service to their country, not in pursuit of pleasure. Any efforts to rescue these people is well worth the risk. The thrill seekers are pursuing their own pleasures under no compulsion, to behave in a dangerous and stupid manner. Any efforts to save them, which risk the rescuers life, are equally insane. If they depended on me the thrill seekers would perish.

Thank you Linda and Happy Thanksgiving to you and yours as well. As usual you go to the heart of the issue. Man is the rational animal, with emphasis on rational. The Dopamine argument casts man as animal, driven by chemically induced biologocal urges. This negates the entire concept of responsibility and is a denial of morality. Everyone is a victim!

Time to go cook my part of the Thanksgiving feast. My Grandkids are waiting for "Sweet Carrots" i.e. Marsala-Butter & Brown Sugar Glazed, Sliced Carrots.

I'm not arguing that at all... why risk a life for an idiot... except an idiot is often your boss and you can quit a job you love or go... but para rescue, seals, green beret, special forces, etc... joined up or tried out for the rush at the beginning... after they age and get some miles on them and don't bounce back as fast as they use to be able to, they usually decide to try something else instead of risking their lives and the lives of others, if they are no longer at their peak abilities.

I agree pafret whole heartily .

There have been times rescuers have died in attempts to rescue thrill seekers that really had no good reason to be in the predicament of their own choice !

Women are the cause of war. Let me explain. I have observed a pasture with a dozen range bulls peacefully grazing, getting along well together, no trouble whatsoever. Run in a couple heifers and the next thing you know all hell breaks loose and the fences come down.

Next scenario. A bar full of guys drinking, shooting pool, watching the game on TV, lying about their conquest, getting along well, fellowship and male bonding. In come a couple of gorgeous girls and the next thing you know, all hell breaks loose.

Conclusion: women are the cause of war and........they're worth it!
