Drinking Alcohol Can Create Modifications In The Architecture Of The Maturing BrainAlcohol can cause alterations in the structure and operation of the blossoming brain, which continues to mature into an individual's mid 20s, and it may have repercussions reaching far beyond teenage years.
In adolescence, brain development is characterized by dramatic modifications to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain disturb everything from emerging sexuality to emotions and cognitive ability.
Not all portions of the juvenile brain mature at the same time, which might put an adolescent at a disadvantage in certain situations. The limbic areas of the brain mature earlier than the frontal lobes. The limbic areas control feelings and are connected with a juvenile's reduced level of sensitivity to risk. The frontal lobes are responsible for self-regulation, judgment, reasoning, problem-solving, and impulse control. Variations in maturation among parts of the brain can result in careless choices or acts and a disregard for consequences.
How Alcohol Alters the Human Brain alcohol alters an adolescent's brain growth in many ways. The effects of underage alcohol consumption on specialized brain functions are discussed below. Alcohol is a central nervous system sedative drug. Alcohol can seem to be a stimulant because, at the start, it depresses the part of the brain that controls inhibitions.
CEREBRAL CORTEX-- Alcohol slows down the cortex as it processes details from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks about something he wants his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that part of the physical body. Alcohol reduces the central nervous system, making the person think, converse, and move more slowly.
FRONTAL LOBES -- The brain's frontal lobes are essential for organizing, creating ideas, decision making, and employing self-discipline.
When alcohol impacts the frontal lobes of the brain, a person may find it difficult to control his or her emotions and impulses. The individual may act without thinking or might even get violent. Consuming alcohol over a long period of time can damage the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the portion of the human brain in which memories are created. When alcohol reaches the hippocampus, a person may have trouble recollecting a thing she or he just learned, like a person's name or a telephone number. This can occur after just a couple of drinks. Drinking a lot of alcohol rapidly can trigger a blackout-- not having the ability to recall whole occurrences, like what she or he did the night before. An individual may find it tough to learn and to hold on to knowledge if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, ideas, and focus. When alcohol goes into the cerebellum, a person might have trouble with these abilities. After drinking alcohol, a person's hands might be so tremulous that they can't touch or grab things properly, and they might fail to keep their equilibrium and tumble.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does an amazing number of the body's housekeeping chores. Alcohol frustrates the work of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, thirst, and the impulse to urinate intensify while physical body temperature level and heart rate decrease.
MEDULLA-- The medulla manages the body's unconscious actions, like an individual's heart beat. It also keeps the body at the best temperature. Alcohol actually cools down the body. Drinking a great deal of alcohol outdoors in chilly climates can cause an individual's physical body temperature level to fall below normal. This hazardous condition is knowned as hypothermia.
An individual may have trouble with these abilities once alcohol goes into the cerebellum. After consuming alcohol, an individual's hands might be so unsteady that they can't touch or take hold of things normally, and they might lose their balance and tumble.
After a person alcoholic beverages alcohol, blood pressure, appetite, being thirsty, and the desire to urinate increase while physical body temperature and heart rate decline.
Alcohol actually cools down the physical body. drinking a lot of alcohol outdoors in cold weather conditions can trigger a person's physical body temperature to fall below normal.
