Role of the gut microbiome in healthy brain development. The gut microbiome plays an essential role in various processes of brain development such as neurogenesis, myelination, microglial maturation, development and maintenance of blood-brain barrier integrity, development of HPA-axis, and HPA-axis stress response. Any alterations in this developmental process can significantly increase the risk for neurodevelopmental disorders.
