Summary

Story summary

A Georgia State University study shows maternal gut microbes impact brain development in newborn mice, especially the paraventricular nucleus (PVN) related to stress and social behavior.
Germ-free mice had fewer neurons in the PVN, suggesting microbial influence starts in the womb.
Researchers call for more studies on maternal microbiota and its effects on offspring health.
