Gut Feelings: How Intestinal Bacteria Regulate Emotion and Behavior


Biologist Sarkis Mazmanian presented “Gut Feelings: How Intestinal Bacteria Regulate Emotion and Behavior.” We were raised to believe that microbes are insidious little creatures that solely cause infections. However, there is now emerging evidence that many bacteria living in our gastrointestinal tract actually confer astounding health benefits. In this talk, Mazmanian, who is Caltech’s Luis B. and Nelly Soux Professor of Microbiology, highlights recent advances showing that specific microbes improve symptoms of anxiety and autism, laying the groundwork to harness the human microbiome to develop revolutionary treatments for neurological diseases that afflict humankind.
