An overgrowth in the gastrointestinal tract of the bacteria Klebsiella in preterm babies was associated with an increased presence of certain immune cells and the development of neurological damage. The findings suggest a link between microbiota and brain development.
Study highlights how the enteric nervous system acts similarly to neural networks in the brain and spinal cord.
The gut microbiome can be harnessed to reverse age-related brain deterioration and restore cognitive function, researchers report.
Early-life exposure to antibiotics could impact brain development in areas associated with emotional and cognitive function, a new study reports. Researchers found penicillin exposure in infant mice altered the microbiome and gene expression in key areas of the developing brain.
Infant boys with a gut bacterial composition high in Bacteroidetes were found to have more advanced cognitive and language skills one year later compared to boys with lower levels of the bacteria.
Researchers identified the gut bacteria E. faecalis as a mediator of social behavior and corticosterone levels in mice.
Gut microbes that metabolize tryptophan secrete indoles that stimulate the development of new neurons in the adult brain.
