Oil sands are deposits of bitumen - heavy oil that must be treated to convert it into crude oil for use in refineries to produce gasoline and diesel fuels. The U.S. Energy Department revised its global oil resource estimates to include the oil sands 174 billion barrels of proven reserves that can be recovered using current technology.

Stress is no fun. Chronic stress can bring abot a wear and tera of one's physical as well as mental health. Experiencing chronic stress day after day is also believed to impact one's learning and emotion.

Now a new study from buffalao university has stated that experiencing short stressful events may possibly have the ability to boost one's learning and memory.

An analysis on rat models was believes to have shown that acute stress can enhance brain functions,via the effect of the stress hormone corticosterone on the brain's prefrontal cortex. Seemingly, the effect of the corticosterone (cortisol in humans) stress hormone on the prefrontal cortex of the brain David Njoku Browns Jersey , which crucial to controlling learning and emotions, was notes to have brought about the positive effect of acute stress on learning and memory.

The researchers specifically showed that acute stress increases transmission of the neurotransmitter glutamate, and improves working memory.

Study author Zhen Yan, profesor of physiology and biophysics at unniversuty at buffalo Myles Garrett Browns Jersey , says, " Stress hormones have both protective and damaging effects on the body. This paper and others we have in the pipeline explain why we need stress to perform better, but don't want to be stressed out,"

In order to test the effect of acute stress on working memory Scientists trained rats in a maze until they could complete it correctly 60 to 70 percent of the time. When the rodents reached this level of accuracy for two consecutive days Nick Chubb Browns Jersey , half were put through a 20-minute forced swim which served as acute stress, and and then were challenged with the maze again.

According to the results, the stressed rats made significantly fewer mistakes as they went through the maze both four hours after the stressful experience and one day post-stress, compared to the non-stressed rats.

To determine if the corticosterone neuropathway was responsible for the improved memory Denzel Ward Browns Jersey , as proposed, researchers injected one group of rats before the forced swim with a medicinal compound that blocks the action of the stress hormone, and injected another group with saline. Results showed that the saline group performed better in the maze than the blocked group.

The researchers also determined that the stressful experience did not increase depression or anxiety-related behavior in the animals.
