>>>>>A recent study have identified the area of the brain responsible for violence. The study which was led by Dayu Lin, PhD, from the Neuroscience Institute at the New York University (NYU) Langone Medical Center and published in Nature Neuroscience had stated that hypothalamus which controls temperature, sleep and hunger is responsible.
This was discovered during a study into the ventromedial hypothalamus, in the brain. According to the study, one element of VMH is thought to control aggression and provides the spark to ignite
violence. Ventromedial hypothalamus is the nucleus of the nucleus of the hypothalamus.
The research was conducted with the study was conducted in mice, which share many brain structures as humans.
The researchers measured the number of attempts the aggressive mice made
to poke their noses through holes leading to another mouse entering
their territory so they could then attack them after the mice were trained to attack the weaker ones.
The researchers also measured the nerve activities in the mouse brain before, during and after they planned to attack. The team also found an increase in the nerve cell activity of the VMHvl as much as
ten-fold during the first moments after the victim mice appeared. "Our study pinpoints the brain circuits essential to the aggressive
motivations that build up as animals prepare to attack," says Lin.
According to her, "the results of the study, argue that the ventrolateral part of the
ventromedial hypothalamus should be studied further as part of future
efforts seeking to correct behaviors from bullying to sexual predation.
