Cryan JF, O'Riordan KJ, Cowan CSM, et al. · Physiological Reviews 2019
Review · Open access
Key finding
Comprehensive mapping of the nerve, immune and metabolic routes between gut microbes and the brain.
In plain language
The most thorough single reference on how gut bacteria could affect the brain. Detailed on mechanism, explicit that human causal evidence is still thin.
How much weight this carries
Real evidence exists, but it is early, limited, or not yet replicated widely.
