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 ...

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 ...

What Is the Limbic System? The limbic system is a part of the brain consisting of several components such as the hippocampus and amygdala and serving many functions within the body. While we have a ...

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

In a recent study published in Neuronal Psychiatry, researchers explored the molecular and cellular processes regulated by tissue inhibitor of metalloproteinases-2 (TIMP2) in the extracellular matrix ...

A. Overview of hippocampal dynamics during movie watching. FMRI data from the hippocampus were measured at the voxel level, and low-dimensional subspaces for two types of novelty and memorability were ...

The hippocampus plays a role in the brain's ability to learn and remember. In the Early Edition of the Proceedings of the National Academy of Sciences, Mody et al. report the use of a microarray ...

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