Neuroendocrine regulation and behavior

Of all of the journal articles that neuroscientist Jane Foster has written in the past 10 years, one stands out. “It was the hardest paper I’d ever published in my life,” says Foster, a professor at McMaster University in Ontario, Canada. Her 2011 study in Neurogastroenterology and Motility showed that mice produced and raised without gut bacteria display changes in anxiety-like behaviors (1). The findings supported a relatively new, and to some researchers, radical, theory: that intestinal microbes can influence the mind. Foster’s manuscript met with skepticism from many reviewers, taking two years to reach publication.
