This is the conclusion the researchers came after a series of experiments in rodents. The animals were subjected to in the course of a brief but severe stress. As a result, rats as shown by observation formed nearly twice as stem cells, which then become the new neurons. After two weeks, researchers conducted tests to find that the rodents showed great intelligence and mental activity and memory in rats significantly improved.
Everybody is used to treat stress as a negative thing, but it#39;s not. Short-term stressful situations are even useful because it makes us to be vigilant and stay alert - commented Daniela Kaufer, author of the study.
That stress, experts say, helps to adapt to the world around animals that live in the natural environment. Short-term stress contributes to the improvement of brain activity has a beneficial effect on mental state. Meanwhile, chronic stress inhibits the production of new neurons, impairing the memory. In addition, the risk of developing certain serious diseases.
