Gut microbes influence behavior

Gut microbes acquired early in life can impact brain development in mice and subsequent behavior, such as decreasing physical activity and increasing anxiety, according to a study published this week in the Proceedings of the National Academy of Sciences.

“This paper opens the door to new studies in at least two directions,” Yale University microbiologist Andrew Goodman, who was not involved in the research, told The Scientist in an email. “First, determining how differences between complete host-associated microbial communities lead to differences in behavior, and second, exploring the contributions of microbes during specific developmental periods in the host.”

Gut microbiota often colonize their hosts early in life, either during pregnancy or following birth, and play an integral role in the health of developing organisms. Previous research has shown that the bacteria affect the development of liver function, the protection epithelial cells afford underlying digestive tissue, gut regulation and the growth of new capillary blood vessels. But this is the first time gut flora have been linked to brain development and behavior.
