The brain is made up of hundreds of millions of nerve cells and delivers thoughts and emotions through electrical signals and chemical reactions. Neurons send messages through the connection of the neurotransmitter, but alcohol suppresses the receptor. Alcohol reaches the brain in 6 minutes and destroys brain cells, especially those in the frontal lobe. These destroyed brain cells are genetically passed on. The frontal lobe damage is especially more serious for adolescents and gives them easy exposure to violence and addiction.
▶An adolescent with alcoholic parents has much lower frontal lobe and cerebellum activity than that of a normal adolescent. This makes it harder for the adolescent to exert self-control and make judgements like the brain of a drunk alcoholic (Journal Alcoholism： Clinical & Experimental Research, April 2012)
