Evidence shows gut microbiome impacts gene expression and neurodevelopment in offspring, suggesting a link to behavior.
Collectively, these data provide proof-of-principle that the maternal gut microbiome has a dominant influence on the neurodevelopment underlying certain offspring behaviors and activities, and selectively affects genome DNA methylation and gene expression in the offspring hippocampus in conjunction with that neurodevelopment.
