Alcohol consumption can trigger changes in the structure and operation of the growing brain, which continues to develop into an individual's mid 20s, and it might have consequences reaching far beyond teenage years.
In adolescence, brain development is defined by remarkable modifications to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotions and judgment.
Not all parts of the adolescent brain mature at the same time, which may put an adolescent at a disadvantage in specific situations. The limbic regions of the brain develop sooner than the frontal lobes.
The way Alcohol Alters the Brain Alcohol alters a juvenile's brain development in several ways. The results of juvenile alcohol consumption on specialized brain activities are discussed below. Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, before anything else, it suppresses the portion of the human brain that governs inhibitions.
CEREBRAL CORTEX-- Alcohol hinders the cortex as it processes information from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks of something he desires his body to undertake, the central nervous system-- the brain and the spine-- sends a signal to that part of the body. Alcohol hinders the central nervous system, making the person think, communicate, and move slower.
FRONTAL LOBES -- The human brain's frontal lobes are very important for organizing, creating concepts, decision making, and exercising self-discipline.
An individual might find it tough to control his or her feelings and urges when alcohol affects the frontal lobes of the brain. The individual may act without thinking or may even become violent. Drinking alcohol over a long period of time can injure the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are created. When alcohol gets to the hippocampus, a person may have difficulty recalling a thing she or he just learned, like a name or a phone 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 happenings, like what exactly she or he did the night before. An individual may find it difficult to learn and to hold on to information if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is very important for coordination, to form thoughts, and attention. A person may have trouble with these skills when alcohol goes into the cerebellum. After consuming alcohol, an individual's hands may be so unsteady that they can't touch or get hold of things properly, and they might lose their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable number of the body's housekeeping chores. Alcohol upsets the work of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, being thirsty, and the need to urinate increase while physical body temperature level and heart rate decline.
MEDULLA-- The medulla controls the physical body's automatic actions, like an individual's heart beat. It likewise keeps the physical body at the ideal temperature. Alcohol in fact chills the physical body. Consuming a great deal of alcohol outdoors in cold weather can trigger a person's physical body temperature to fall below normal. This harmful condition is termed hypothermia.
An individual may have trouble with these abilities once alcohol gets in the cerebellum. After drinking alcohol, a person's hands may be so unsteady that they cannot touch or get hold of things normally, and they may fail to keep their equilibrium and tumble.
After an individual drinks alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while body temperature levels and heart rate decrease.
Alcohol in fact chills the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can cause a person's physical body temperature to drop below normal.
