Sex and aggression - twins

Researchers found that specific areas in the brain responsible for the sex and violence, rather tightly linked. But fortunately, experiments in mice have shown that during mating, "aggressive" cells are suppressed.

Researchers at New York University have identified neurons in the mouse brain, which are responsible for aggression . Then was bred by genetic rodent species for which these neurons are activated when the blue light. As soon as the blue beam to illuminate the cell and mouse instantly became very aggressive, attacking their fellows, and both male and female.

But in further experiments, the researchers found that the number of cells responsible for the mating process, inhibits the action of "aggressive cell" if the mouse sex . "Block mating behaves as a gateway for the unit aggression Actively suppressing "aggressive" neurons, when there is a potential partner, "- said in an interview with Nature Today neurologist Dong Lin, who led the study.

As suggested by Lin and his team, the relationship between the blocks aggression   and sex in the brain of mice helps rodents to respond properly to the invasion of strangers, of whatever sex they belong to. But if this turns out to be an outsider unfamiliar female aggression suppresses the zone area of ​​sex, and mouse into the battle.

When a rodent is committed to mate, then the reverse process, in which area of ​​sex prevails over the area aggression .

Now scientists have hypothesized that the same connection can exist in the human brain. It remains to conduct appropriate studies in humans.
