A study in mice concluded that memory problems associated with age may be driven by our gut microbiome and that the vagus nerve may be key to reversing it.

Researchers identified in mice a microbiome–gut–brain pathway in which age-associated changes in gut microbes increase medium-chain fatty acids that impair vagal sensory signaling and hippocampal ...

A team of researchers has shown that noninvasive electrical stimulation of the vagus nerve through the ear can reverse memory ...

Researchers have used mouse models to study how cocaine addiction alters the brain, illuminating why relapse is common as ...

As mice age, changes in the microorganisms in their guts contribute to cognitive decline by altering signalling between the gut and brain.

Lysosomes were once viewed mainly as cellular waste disposers, but are now recognized as key hubs for nutrient sensing and ...

Scientists at Arc Institute and Stanford University have discovered that age-related memory loss may be driven by changes in the gut rather than the brain itself. In a study published in Nature, ...

Although we've all experienced the sensation of "eating" with our eyes and noses before food meets mouth, much less is known about the information superhighway, known as the vagus nerve, that sends ...

Studying the minds of octogenarians with surprising cognitive resilience shows how it's possible to maintain a youthful brain well into old age.

Voluntary exercise reshapes gut microbiota and tryptophan metabolism, with consequences for the hippocampus, the ...

Something happens when a rat starts running. Not just the obvious things, the faster heart, the warming muscles, the rhythmic percussion of paws against the wheel. Something quieter. Something that ...

A single session of physical exercise can spawn a boost of neural activity in brain networks that underlie learning and memory, according to a new study led by the University of Iowa.
