Alcohol Consumption Can Trigger Alterations In The Architecture And Function Of The Blossoming BrainAlcohol can trigger changes in the architecture and function of the growing brain, which continues to mature into an individual's mid 20s, and it may have consequences reaching far beyond adolescence.
In adolescence, brain development is defined by remarkable changes to the brain's structure, neural connections ("circuitry"), and physiology. These transformations in the brain alter everything from developing sexuality to emotionality and cognitive ability.
Not all parts of the juvenile brain mature at the exact same time, which may put an adolescent at a disadvantage in particular circumstances. The limbic regions of the brain develop earlier than the frontal lobes.
How Alcohol Alters the Human Brain Alcohol disturbs a juvenile's brain development in many ways. The consequences of minor drinking on specific brain activities are discussed below. Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, initially, it depresses the portion of the brain that regulates inhibitions.
CORTEX-- Alcohol impedes the cerebral cortex as it processes details from an individual'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 a signal to that part of the physical body. Alcohol reduces the central nervous system, making the individual think, converse, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are very important for advanced planning, creating concepts, decision making, and using self-discipline.
A person might find it hard to control his or her feelings and urges once alcohol impacts the frontal lobes of the brain. The individual may act without thinking or may even get violent. Consuming alcohol over a long period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the human brain in which memories are made. Once alcohol reaches the hippocampus, a person might have trouble recalling a thing he or she just learned, like a name or a telephone number. This can occur after just one or two alcoholic beverages. Drinking a lot of alcohol quickly can trigger a blackout-- not being able to remember entire occurrences, like what he or she did last night. An individual might find it hard to learn and to hold on to knowledge if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, to form thoughts, and awareness. When alcohol goes into the cerebellum, a person might have trouble with these abilities. After consuming alcohol, a person's hands might be so tremulous that they can't touch or take hold of things properly, and they might lose their balance and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an amazing variety of the physical body's housekeeping tasks. alcohol upsets the operation of the hypothalamus. After an individual consumes alcohol, blood pressure, hunger, being thirsty, and the need to urinate intensify while physical body temperature and heart rate decline.
Alcohol in fact cools down the physical body. drinking a lot of alcohol outdoors in cold weather conditions can cause an individual's physical body temperature to fall below normal.
An individual may have trouble with these abilities once alcohol enters the cerebellum. After consuming alcohol, a person's hands may be so unsteady that they can't touch or get hold of things properly, and they might fail to keep their balance and tumble.
After an individual drinks alcohol, blood pressure, appetite, being thirsty, and the urge to urinate increase while body temperature and heart rate decline.
Alcohol in fact chills the body. Drinking a lot of alcohol outdoors in cold weather conditions can cause an individual's physical body temperature level to fall below normal.
