Urban living and infant brain development: a gut-brain link

Official title: Impact of Urbanicity on Infant Brain Structure and Function via the Gut-Brain Axis

Funded at Henry Ford Health + Michigan State University Health Sciences · NIH-11451272 · Data updated 2026-11-12

A short study in infants will explore how growing up in cities might shape brain development and gut microbes, which could influence later mental health.

Who could benefit from this research

Could help

Infants and their families in urban and non-urban settings who are part of the ORIGINs imaging cohort or similar infant imaging studies.

Less likely to help

Families not participating in imaging or stool-sampling components may not experience direct benefits.

What this research studies

This NIH-funded project will look at infants from urban and non-urban settings to see how the environment influences brain structure and function in the first year of life. Researchers will examine the gut microbiome as a possible mechanism linking city life to brain development, using existing imaging data from the ORIGINs consortium. The goal is to identify neural and microbial patterns that relate to early-life urban exposure, laying the groundwork for future interventions. The study is designed to be observational and non-invasive, focusing on brain imaging and stool samples collected during the first year.

Why it matters

Potential benefit: If successful, the findings could inform strategies to support healthy brain development in urban-born children and reduce risk factors for later mental health challenges.

How similar studies have gone: Prior work supports links between early environment, gut microbiome, and brain development, but this project tests a specific urbanicity-brain-microbiome pathway in infancy.
