Alcohol Not Help Forget Bad Memories

Alcohol Not Help Forget Bad Memories.

Teenagers often drink alcohol to cope with or forget the traumatic experience. Shortcuts is considered to relieve feelings of sadness, disappointment, or a wound that was their experience. However, health experts warn those who drink alcohol tend to be excessively long wrestled with the trauma.

Researchers from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and UNC’s Bowles Center for Alcohol Studies found that alcohol can change the key functions in the brain that affects a person’s character.

In a study published in the journal Nature Neuroscience, the researchers wanted to test whether mice afraid of certain sounds. The researchers also give an electric shock to the rats at any time. Researchers tested a group of mice that had been given alcohol by the excess amount. Meanwhile, the other group of mice was given no alcohol at all.

During the experiments, an electric shock to the rats stop accompanied by a special tone. Gradually, the mice that were not given alcohol used to tone and learn when it is not dangerous anymore. However, rats that were given alcohol to react with fear. Rat in a rigid position every time they hear a sound, even when it is not accompanied by an electric shock.

“Basically, our study shows that exposure to alcohol can cause cognitive deficits at the center of the brain, which controls the emotional centers in the brain,” said Thomas Kash, PhD, assistant professor of Pharmacology of the University of North Carolina School of Medicine, which is one a researcher.

Then, the researchers compared the brains of rats under the influence of alcohol and normal rat brain. Researchers found significant differences in brain structure, especially in the pre-frontal cortex. This area is associated with cognitive function, social behavior, decision-making and behavior modulation intensif.Pengamatan found, the shape of nerve cells in the brain in both groups of mice was different.

The main receptors known as NMDA (N-methyl-D-aspartate) in rats with alcohol looks depressed. Receptor function is associated with all the signs of addiction such as alcohol dependent, addiction, and withdrawal.

“We do not just look at the emotional harm that alcohol alone. Results of this study show how alcohol interfere with the function of brain circuits that are very specific,” says scientist Andrew Holmes, PhD, of the NIAAA.
