In an exciting new development, scientists are beginning to find evidence for a direct role of bacteria in modulating animal behavior. A new study published in Nature Microbiology has found that microbial populations in the gut can influence behavior in a variety of animals, including humans. This research is the first to demonstrate a link between gut bacteria and behavior in such a wide range of species. The study found that gut bacteria can affect the behavior of animals in areas such as communication, social behavior, and aggression. The researchers also suggest that manipulating the gut microbiome could offer a potential strategy for treating behavioral disorders in humans.
