Cartoon showing communication between the brain and microbiome of the gut. The gut-brain axis is the biochemical signalling that takes place between the gastrointestinal tract (GI tract) and the central nervous system (CNS). The relationship between gut flora and humans is not merely commensal (a non-harmful coexistence), but rather a mutualistic relationship. Research has shown gut flora might play a role in anxiety and mood disorders.
