Interpreting the microbiome-brain-behavior connection

[brhowell]

Has anyone been working with microbiologists to really dig into the mechanisms underlying the links between the brain and the microbiome? I attended several presentations at the annual meeting that found relationships between the gut microbiome and the brain, but not many went beyond just presenting correlations between either diversity or abundance of single genera. I would love to learn more about the specific roles of the microbes that are affected by treatments/manipulations, or are found to predict neural and/or behavioral states, particularly during development.
