Scientists have discovered a type of intestinal bacteria that can directly affect the brain. The findings are expected to uncover new ways to control depression and other psychiatric disorders.
Previously, researchers have long suspected that the bowel has to do with the brain, because abnormalities in these body parts associated with psychic diseases in humans such as anxiety and depression.
To be sure, researchers from University College Cork in Ireland provides Lactobacillus rhamnosus JB-1, bacteria that commonly live in the intestines of humans into mice.
Apparently, the water intake of rats fed broth containing bacteria that have behaviors associated with stress, anxiety and depression are much lower compared to the broth without bacteria.
Mice given bacteria also have the stress hormone corticosterone levels are lower when facing stressful situations such as when she was placed inside the barrier. And since rats can be a good example in studying the human brain, researchers say the findings could also be applied to humans.
"By utilizing gut bacteria, you have a very strong and broad-related brain chemistry and behavior," said John Cryan, researchers from University College Cork, as quoted by LiveScience, September 4, 2011.
Without exaggerating everything, said Cryan, these findings open up the concept that we can develop therapies that can treat psychiatric disorders by targeting the gut. "You can drink yogurt with probiotics in it and not using antidepressants," he said.
However, Cryan said, yogurt is not yogurt, which we used to drink every day. We do not recommend you go to the supermarket and do this.
