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

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 ...

Memory is not a recording device. It doesn't play back events like a video camera would. Instead, it's a remarkably active, ...

While neurogenesis—the growth of new brain cells—typically slows with age, superagers produce new neurons in the hippocampus at twice the rate of healthy older adults. In contrast, individuals with ...

Researchers used single-nucleus RNA sequencing and chromatin accessibility profiling to map human hippocampal neurogenesis across adulthood, aging, and Alzheimer’s disease. They found that chromatin ...

"This is biological proof that their brains are more plastic, and a real discovery that shows that neurogenesis of young ...

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 ...
