The biochemical mechanism by which alcohol exerts its effects on the brain has been uncovered

Although alcohol has been consumed for millennia for its intoxicating properties, only recently has the biochemical mechanism by which the effect is caused been elucidated. Researchers, utilizing results of recent research, have proposed a model that appears to explain the effects. If further research confirms the research, then a potential new path for treatment of alcohol abuse may be found.
