what is the microbiome gut brain axis?

The microbiome-gut-brain axis (MGB) is a term used to describe the bidirectional communication between the gut microbiota and the brain. The gut microbiota has been shown to influence various behaviors and cognitive functions, while also being sensitive to changes in the environment, including psychological stressors. This suggests that there is a complex two-way dialogue between the gut microbiota and the brain that may impact both physical and mental health.
