Alcohol consumption can trigger changes in the structure and operation of the blossoming brain, which continues to grow into a person's mid 20s, and it might have repercussions reaching far beyond adolescence.

In adolescence, brain development is characterized by dramatic modifications to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These changes in the brain alter everything from emerging sexuality to emotionality and cognitive ability.

Not all component parts of the adolescent brain mature simultaneously, which might put a youth at a disadvantage in particular situations. The limbic areas of the brain mature earlier than the frontal lobes. The limbic areas regulate feelings and are associated with a juvenile's decreased sensitivity to risk. The frontal lobes are responsible for self-regulation, judgment, reasoning, problem-solving, and impulse control. Variations in maturation amongst parts of the brain can result in rash decisions or acts and a disregard for repercussions.

Ways Alcohol Affects the Human Brain
Alcohol alters a juvenile's brain development in numerous ways. The consequences of minor drinking on specialized brain functions are discussed below.
Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, to begin with, it depresses the part of the human brain that regulates inhibitions.

CORTEX-- Alcohol impedes the cerebral cortex as it works with information from a person's senses.

CENTRAL NERVOUS SYSTEM-- When a person thinks of something he desires his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that part of the body. Alcohol reduces the central nervous system, making the person think, communicate, and move more slowly.

FRONTAL LOBES -- The human brain's frontal lobes are important for advanced planning, forming ideas, decision making, and exercising self-control.

Once alcohol impairs the frontal lobes of the brain, an individual might find it tough to manage his or her emotions and impulses. The person might act without thinking or may even become violent. Consuming alcohol over a long period of time can damage the frontal lobes permanently.

HIPPOCAMPUS-- The hippocampus is the portion of the brain in which memories are created.
Once alcohol reaches the hippocampus, a person might have difficulty remembering a thing she or he just learned, such as a name or a telephone number. This can take place after just a couple of drinks.

Drinking a lot of alcohol rapidly can trigger a blackout-- not having the ability to recall whole events, like what exactly she or he did the night before.
If alcohol harms the hippocampus, an individual may find it hard to learn and to hold on to knowledge.

CEREBELLUM-- The cerebellum is essential for coordination, thoughts, and focus. An individual might have trouble with these abilities when alcohol goes into the cerebellum. After drinking alcohol, an individual's hands may be so shaky that they can't touch or get hold of things normally, and they might fail to keep their equilibrium and tumble.

HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable variety of the body's housekeeping chores. Alcohol upsets the work of the hypothalamus. After a person drinks alcohol, blood pressure, hunger, thirst, and the impulse to urinate increase while body temperature and heart rate decrease.

Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger an individual's physical body temperature level to drop below normal.

An individual might have difficulty with these skills when alcohol gets in the cerebellum. After drinking alcohol, an individual's hands may be so shaky that they cannot touch or take hold of things properly, and they might lose their balance and tumble.

Alcohol in fact chills the body. Drinking a lot of alcohol outdoors in cold weather can cause a person's physical body temperature to fall below normal.
