Fights are won and lost in the brain

In humans and other social animals, fighting is an important mode of maintaining a group's social structure. The question of how such aggression is regulated can now be answered, at least for a certain kind of fish, and the key is not brawn, but the brain. Researchers at the RIKEN Brain Science Institute have found that a deep-brain structure called the habenula contains two neural circuits that work in a complex interplay to influence whether a fight will be a win or loss.
