Alcohol can trigger modifications in the architecture and function of the blossoming brain, which continues to develop into a person's mid 20s, and it may have consequences reaching far beyond adolescence.
In adolescence, brain development is defined by remarkable modifications to the brain's structure, neural connections ("electrical wiring"), and physiology. These transformations in the brain alter everything from developing sexuality to emotionality and judgment.
Not all parts of the juvenile brain mature at the exact same time, which might put a juvenile at a disadvantage in certain circumstances. The limbic areas of the brain mature earlier than the frontal lobes.

The way Alcohol Alters the Human Brain
Alcohol alters a juvenile's brain development in several ways. The consequences of juvenile alcohol consumption on specialized brain functions are explained below.
Alcohol is a central nervous system sedative. Alcohol can seem to be a stimulant because, before anything else, it depresses the portion of the human brain that manages inhibitions.
CEREBRAL CORTEX-- Alcohol slows down the cerebral cortex as it processes information from a person's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he wants his body to do, the central nervous system-- the brain and the spine-- sends a signal to that portion of the body. Alcohol impedes the central nervous system, making the person think, speak, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are essential for planning, creating ideas, decision making, and using self-discipline.
Once alcohol impairs the frontal lobes of the brain, a person might find it hard to control his/her feelings and impulses. The person might act without thinking or might even get violent. Consuming alcohol over an extended period of time can injure the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the human brain in which memories are generated.
When alcohol gets to the hippocampus, a person might have trouble remembering something she or he just learned, like a name or a telephone number. This can take place after just a couple of drinks.
Drinking a lot of alcohol quickly can trigger a blackout-- not having the ability to remember entire happenings, like what he or she did last night.
A person might find it difficult to learn and to hold on to information if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is very important for coordination, thoughts, and awareness. A person might have difficulty with these skills when alcohol gets in the cerebellum. After consuming alcohol, an individual's hands may be so shaky that they cannot touch or get hold of things properly, and they might fail to keep their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable variety of the physical body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After an individual consumes alcohol, blood pressure, hunger, thirst, and the need to urinate increase while physical body temperature level and heart rate decrease.
MEDULLA-- The medulla controls the physical body's unconscious actions, such as a person's heartbeat. It likewise keeps the physical body at the best temperature. Alcohol actually chills the body. Drinking a lot of alcohol outdoors in chilly climates can trigger a person's body temperature to fall below normal. This dangerous condition is termed hypothermia.
A person might have trouble with these abilities when alcohol goes into the cerebellum. After consuming alcohol, a person's hands might be so tremulous that they cannot touch or grab things properly, and they might fail to keep their balance and fall.
After a person alcoholic beverages alcohol, blood pressure, hunger, being thirsty, and the desire to urinate increase while body temperature and heart rate decline.
Alcohol in fact chills the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger a person's body temperature to drop below normal.
