Memory Loss Is Fuelled by Gut Microbes in Ageing Mice

The gut microbiome may influence brain aging, mouse study suggests

A communication pathway between the brain and the gut may be integral to how well the brain holds on to memories

‘Tour de force’ mouse study shows a gut microbe can promote memory loss

Research suggests the microbiome may contribute to cognitive decline—but its relevance in humans is unclear

Gut microbes affect cognition during ageing

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

Reversing Memory Loss via the Vagus Nerve

Scientists prove that "brain aging" is driven by signals in the gut, and reversing the process is as simple as a nerve "reset."

Memory loss is fuelled by gut microbes in ageing mice

Edward Chen in Nature: A species of gut bacteria that proliferates as mice get older plays a part in cognitive decline, a study finds1. Researchers determined that the bacterium interferes with signalling along sensory nerves that connect to the brain. Although the experiments were conducted in mice, the gut–brain circuit that the team identified “is likely conserved in humans”, says David Vauzour, a biochemist at the University of East Anglia i…
