Gut microbiota regulates stress responsivity via the circadian system

Gut microbes are known to modulate stress responsivity and behavior. Tofani et al. demonstrate that such modulations occur via the circadian system. The oscillations in gut microbiota composition regu...

A brilliant keynote today by @jfcryan.bsky.social at the EBPS meeting on how the gut shapes behavior, including striking causal evidence for microbiome’s role in social behaviors. A masterclass of body-brain complexity! & with an impressive depth of data and the right dose of humor!

Briefly, it demonstrates that the gut-brain vagal axis exerts a considerable influence on dopamine-dependent reward-related processes...

What are the many “known unknowns” on the microbiome, exposome, & cognitive development?
@maburto.bsky.social @jatinnagpal.bsky.social @jfcryan.bsky.social https://loom.ly/oUMFc0w

Microbiome, Exposome, and Cognitive Development: The Known Unknowns | Annual Reviews

The gut microbiota, composed of trillions of microorganisms, plays a key role in bidirectional communication between the gut and brain, particularly during early life. The first two postnatal years represent a critical window when the exposome—the totality of all environmental exposures—shapes neurodevelopment via the microbiota–gut–brain axis. Exposome factors such as diet, birth mode, antibiotic use, infections, and xenobiotics can alter microbial composition and function, with downstream e...
