The mystery of why alcohol makes people violent has finally been solved.
Scientists recruited 50 young men and asked them to consume either vodka or placebo drinks which were alcohol free.
They found that after just two drinks activity diminished in the prefrontal cortex of the brain – an area which is involved in tempering a person’s level of aggression.
Although experts had suspected for some time that the prefrontal cortex was involved, it is the first time it has been seen happening.
Dr Thomas Denson of the University of New South Wales in Australia, said: “Although there was an overall dampening effect of alcohol on the prefrontal cortex, even at a low dose of alcohol we observed a significant positive relationship between dorsomedial and dorsolateral prefrontal cortex activity and alcohol-related aggression.
“These regions may support different behaviors, such as peace versus aggression, depending on whether a person is sober or intoxicated.”
