Alcohol Consumption Can Trigger Changes In The Architecture And Operation Of The Blossoming BrainAlcohol can trigger alterations in the architecture and operation of the growing brain, which continues to grow into a person's mid 20s, and it might have repercussions reaching far beyond teenage years.
In adolescence, brain growth is identified by dramatic changes to the brain's architecture, neuron connectivity ("circuitry"), and physiology. These transformations in the brain disturb everything from developing sexuality to emotions and judgment.
Not all parts of the adolescent brain mature at the exact same time, which might put a juvenile at a disadvantage in specific circumstances. The limbic regions of the brain develop earlier than the frontal lobes.
Ways Alcohol Alters the Human Brain Alcohol disturbs an adolescent's brain development in several ways. The consequences of underage drinking on particular brain functions are discussed below. Alcohol is a central nervous system depressant. Alcohol can appear to be a stimulant because, at the start, it suppresses the part of the human brain that manages inhibitions.
CORTEX-- Alcohol reduces the cerebral cortex as it works with information from a person's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he desires his body to do, the central nervous system-- the brain and the spine-- sends a signal to that part of the body. Alcohol impedes the central nervous system, making the individual think, speak, and move more slowly.
FRONTAL LOBES -- The brain's frontal lobes are essential for organizing, forming concepts, making decisions, and using self-control.
A person may find it difficult to manage his or her feelings and urges when alcohol impacts the frontal lobes of the brain. The person might act without thinking or might even become violent. Consuming alcohol over an extended period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the human brain in which memories are generated. Once alcohol gets to the hippocampus, a person may have difficulty remembering something she or he just learned, such as a name or a telephone number. This can occur after just one or two drinks. Drinking a great deal of alcohol rapidly can trigger a blackout-- not having the ability to recall entire happenings, like what exactly she or he did last night. If alcohol harms the hippocampus, a person may find it difficult to learn and to hold on to information.
CEREBELLUM-- The cerebellum is necessary for coordination, ideas, and focus. A person might have difficulty with these skills once alcohol goes into the cerebellum. After consuming alcohol, a person's hands may be so unsteady that they cannot touch or get hold of things properly, and they may fail to keep their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible number of the body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while physical body temperature level and heart rate decline.
MEDULLA-- The medulla manages the body's automatic actions, such as an individual's heart beat. It also keeps the physical body at the best temperature. Alcohol actually cools down the body. Drinking a lot of alcohol outdoors in cold weather can cause an individual's physical body temperature to drop below normal. This dangerous situation is termed hypothermia.
An individual may have difficulty with these abilities 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 lose their balance and fall.
