Neuroscientist of the gut–brain axis
Dr. John Cryan is a neuroscientist and professor at University College Cork. His pioneering work on the gut–brain axis shows how microbes influence mood, memory, and mental health through biochemical signaling.
Based on John F. Cryan & Timothy G. Dinan, Mind-altering microorganisms: the impact of the gut microbiota on brain and behaviour (Nature Reviews Neuroscience, 2012), summarised and reframed by Insights.
