Mind-Altering Microbes

Elaine Hsiao talks about her work at Caltech on how the microbes in your gut affects your brain and your behaviour. She uncovered the role for the commensal microbiota (the gut microbes) in regulating autism-related behaviours and metabolism. She is currently studying the mechanisms by which microbes affect host production of neuroactive molecules (like serotonin) and how they influence health and disease. The microbial gut transplant with happy bacteria is a step closer!
