New research found that intestinal bacteria has affected the brain development.
According to foreign media reports, though you are coordinated by the billions of abnormal human cells, but these cells can easily be living in your body and surpassed the number of bacteria in the body, and they are for you to add additional 2 kg body weight. These bacteria are not freeloader passing, many bacteria are actively helping us digest food and prevent infection. Now there is evidence that these organisms may also have a profound impact on the brain. So if we can make adjustments for these organisms, so that we become healthier, happier and even more clever?
An early test of anatomy and neurology professor at the University of Hancock John Cryan showed that in mice subjected to the pressure of living gut bacteria diversity will be severely reduced. Cryan said: “gut bacteria can help normal brain development if there is no presence of microorganisms, your brain structure and function will be significant changes..” A Japanese research team also found that mice without any intestinal bacteria has exaggerated The stress response, but also produce more hormones than normal mice.
However, this effect can be sterile mice by injecting a symbiotic intestinal bacteria Bifidobacterium infantis weakened. Cryan’s team found that this effect even in healthy mice can be reproduced. But why gut bacteria can affect the brains? Information via several different ways to pass between the organs. Information is possible by hormones in the blood, immune cells, or vagus nerve transmission, and they extend from the brain to the gut. By these paths will have the behavior of an organ on the other.
Cryan team human trials now under way, in order to understand the healthy volunteers after adjusting gut microbes, whether we can improve their cognitive abilities. Cryan said: “Diet is probably the biggest factor in microbiota composition varied diet will make you get a variety of microorganisms..” Researchers are studying whether certain combinations of foods can change microorganisms, thereby improving cognition. Cryan very optimistic for the future, he said:. “Research in this area is now rapid progress, but still in its early stages, we still need to make many important research.”
