The New York Academy of Sciences

The brain is affected by bodily changes—including microbiome composition—that influence cognition and behavior. This eBriefing will explore the interaction between the brain, gut & microbiome, with a focus on how the microbiome influences developmental, neuropsychiatric, and immune-related disorders, including socioaffective processing disorders such as autism.

In this eBriefing, You’ll Learn:

  • How the microbiome is seeded and maintained throughout life
  • How stress effects health of the microbiome
  • How changes in microbiome composition result in changes in behavior
  • The latest research in therapies targeting microbiome
