A group of scientists from the University of North Carolina at chapel hill found in the human brain two areas of interrelated with the formation of alcoholism. The extended amygdala and ventral tegmental area in certain kinds of interactions could contribute to the excessive use of alcohol and other drugs, says Biological Psychiatry.

The extended amygdala is responsible for the formation of drug dependence, anxiety and stress after the effect of intoxication. The ventral tegmental area affect the system of reward and complements the amygdala.

Experiment on laboratory mice confirm the theory of researchers. According to her, the more a person uses alcohol, the greater the reward is giving him brain. This happens without regard to harm from alcohol. The result is alcohol dependence.
