@How bacteria control human mood?

We have become human beings for our mind, our thinking power and emotion. But recently a new and thought-provoking idea is arising from headaches, where it is claimed that all the bacteria or microbes inside the body of the human body.

Especially the gut-brain, have all the invisible hands in them. Modern technology is so advance. Science is still trying to know how many millions of micro-organisms live in ours, and how they affect their physical condition. However, there is a similar link between these types of microbes for frustration, autism and brain disorders that cause neurons. Researchers believe that they have learned about some bacteria that can be used to improve mental health. They are saying 'Mood Microbes' or 'Psycho-bio-tic'.
