European scientists were able to determine how intestinal bacteria can influence the psychological state of the person and his mood.
Early studies in mice have shown the influence of intestinal microbes on the behavior of rodents, and the few studies involving humans proved that the amount of data of microbes is altered in depression.
Belgian scientists conducted a study involving 1054 volunteers who were invited for evaluation of the normal microbiome. 173 participants were diagnosed with depression.
Indicators of microbiomes compared with the other participants, the emotional state which was normal. It turned out that the depressed people were missing microbes caprock and dialister.
To establish a link between the microbes in the mood, scientists have compiled a list of 56 substances that play an important role in the functioning of the nervous system.
These substances are produced or destroyed by intestinal microbes. The researchers found that capacocha, apparently, there is a connection with the processing of dopamine, which is called the hormone of happiness.
Its decrease can cause depression. However, scientists do not know how microbial compounds of the gut can affect the brain.
It is assumed that this connection is provided by the vagus nerve.
