Hippocampus when impaired by alcohol, play an important role in memory

Further explanation

The brain is the body's control center. The brain is part of a body system called the Central Nervous System. CNS is responsible for taking in information through the senses, motor function, thinking, understanding, and reasoning. While all body systems feel the effects of alcohol, the CNS is particularly sensitive.

There are parts of the brain that affected by alcohol, such as:

  1. The cortex, responsible for judgment and reasoning.
  2. The cerebellum, responsible for balance and coordination.
  3. The hypothalamus, for regulating appetite, temperature, pain, and emotions.
  4. The amygdala, for regulating social behavior.
  5. The hippocampus, responsible for the center of memory and learning.

When impaired by alcohol, hippocampus is affected first, causing behavior to become looser and less guarded. Hippocampus is the part of the brain that stores memory. It is still maturing during adolescence. The small amount of alcohol can make teens forget what they did or learned while they were drinking.

The correct statement from all the given options is a) hippocampus.

Further Explanation:

Brain is one of the important organs of the body as it controls the vital functions of the body. Factor that affects the brain are stress, diet, sleep, infection, alcohol, drugs etc.

Alcohol can lead to changes in the brain as it can damage the neurons in the central nervous system as it crosses the blood brain barrier. As alcohol reaches the brain it starts killing neurons and affect the system which helps in decision making, regulating emotions etc.

Effect of alcohol on hippocampus

• Hippocampus is that part of the brain which helps in storing of memory. It helps in managing the learning. If the hippocampus is affected it may lead to loss of memory. Alcohol consumption may lead to disruption of hippocampus as it decreases the electrical activity of neurons by binding to specialized proteins which are present in neuronal membrane. The decreased production of impulses in the hippocampus disrupts the formation of the short term memory and long term memory. Damage may vary depending upon the disruption of hippocampus.  

• If the cells degenerate in the hippocampus it may lead to Alzheimer’s disease.
