Age-associated gut microbiota impairs hippocampus-dependent memory in a vagus-dependent manner

Damien Rei, Soham Saha, Marianne Haddad…·Pierre‐Marie Lledo

This study shows that age-related gut microbiota impair hippocampus-dependent memory via a vagus nerve-dependent mechanism, and suggests pharmacogenetic vagus stimulation as a potential therapeutic strategy.
