New area in gut-brain research

Bacteria living in the human gut have strange influence over mood, depression and more, but it has been unclear exactly how belly-dwelling bacteria exercise remote control of the brain (…). Now research in rodents suggests that gut microbes may alter the inventory of (…) molecules that help keep cells in working order by managing protein production — in brain regions involved in controlling anxiety. (…) The way we think and feel might be able to be controlled by our gut microbiota. (…) It’s heading into a new area in gut-brain research that hasn’t been pursued.
