Séminaire impromptu - John F Cryan“A Gut Feeling About the Brain: Microbiome as a Key Regulator of Neurodevelopment and Behaviour”

Abstract :

Prof. Cryan's current research interests include the neurobiological basis of stress-related neuropsychiatric disorders including depression, anxiety and drug dependence. Moreover, his group is also focused on understanding the interaction between brain, gut & microbiome and how it applies to stress and immune-related disorders, including irritable bowel syndrome and obesity and neurodevelopmental disorders such as autism. He is also interested in applying novel approaches to facilitate drug/siRNA delivery to the brain in vivo.
