Alcohol Consumption Affects Ability To Overcome Fear

Posted by diamond stud 4:58 AM, under ,, | 8 comments

Doctors have known for a long time that alcoholism is associated with increased risk of anxiety, such as PTSD (post traumatic stress disorder), and that heavy drinkers are more likely to be involved in automobile accidents and/or domestic violence situations.

Now, new research by experts at the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and UNC's Bowles Center for Alcohol Studies, published online September 2, 2012 in Nature Neuroscience has determined that high alcohol consumption rewires brain circuitry, which suggests that it is more difficult for people who drink heavily to bounce back from a traumatic event in their lives. 

Thomas Kash, PhD, assistant professor of pharmacology at the University of North Carolina School of Medicine commented: "There's a whole spectrum to how people react to a traumatic event. It's the recovery that we're looking at - the ability to say 'this is not dangerous anymore.' Basically, our research shows that chronic exposure to alcohol can cause a deficit with regard to how our cognitive brain centers control our emotional brain centers."

For their trial, the experts split mice into two groups. The first was given the equivalent amount of alcohol for humans that is twice the limit allowed for driving. The second was not given any alcohol at all. The mice were then taught by use of small shocks to be scared of a certain sound the researchers played. 


The researchers observed that when the sound played over and over without the shock, the mice who were in the no alcohol group eventually stopped being scared of the tone. On the other hand, the mice who had high exposure to alcohol were scared of the noise, making them stand completely motionless every time they heard it - for a long time after the shocks were not present.

The authors explain that these findings are very much like the ones seen in individuals who suffer from PTSD, with these people taking longer to get over a certain fear even when the situation is not one that they should be scared of anymore. 

They believe that this evidence stems back to the neural circuitry of the mice that were chronically exposed to alcohol. When analyzing the brains of the two different groups of mice, the researchers found that the nerve cells found in the prefrontal cortex of the brains of the mice who had been exposed to alcohol, were shaped differently than the mice who had not been exposed to any alcohol. They also noticed that NMDA, an important receptor in the brain was not as active in the mice who consumed alcohol.


The NES mihealth is able to detect disturbances within the human body field - and, unlike any other similar devices on the market - it is also capable of transmitting bio information (NES Information®) to the body at frequencies that match specific bones, muscles, joints and other parts of the body.

Our muscles become deflated with age, losing their moisture like a dry sponge. Acupuncture restores the natural internal irrigation so the 'sponge' is plumped up again and the wrinkles disappear. Treatments include addressing the facial muscles directly because the electro-stimulation of the natural electric charge in the muscle re-establishes the natural flow and the charge/discharge cycle. This enlivens the tissue. Fluids can move through as they did in youth. Kathleen's PEMF instrument quickens the process of rebuilding skin and muscle tissue, while improving the face's senses: vision, hearing, brain power, and also alleviating depression, as confirmed in numerous studies!

I'm really loving the theme/design of your website. Do you ever run into any internet browser compatibility problems? A handful of my blog visitors have complained about my website not operating correctly in Explorer but looks great in Firefox. Do you have any advice to help fix this problem?


I was wondering if you ever thought of changing the structure of your site?Its very well written; I love what youve got to say.But maybe you could a little more in the way of content so people could connect with it better.Youve got an awful lot of text for only having one or two pictures.
Maybe you could space it out better?

If a couple is pro-life, that's fine, but if they think that being pro-life is simply a question of maximizing the number of pregnancies in the world at whatever cost and in whatever way we can imagine, then they're not grappling with the issues seriously at all and should be told as much. Here i suggest couples to go INDIA for IVF surrogacy, then you must search for Surrogacy India, Surrogate mother India, IVF India, IVF clinic India & IVF cost india. I found Go Surrogacy for this treatment in India. Hope you also like these.
