The Effects of the Gut Microbiome on Stress and Mood

The study from 2011 was one of the first to really clearly show that behaviors could be transferred along with a gut microbiome, at least in mice. There have since been follow-up studies, also on mice, drawing more connections between the gut and mood disorders and stress and personality traits. Katarina says she has started to see more research being done across species to see if same kinds of effects hold up.
