Psychobiotics

Psychobiotics is a self-paced learning path in Biological Sciences, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the biological link between intestinal microbes and human mental health status; describe the composition of the human gut microbiome; define psychobiotics as specific bacterial strains targeting mental wellness.

Conductor

The Conductor

Welcome aboard this journey into the gut-brain axis. We will explore how tiny microbes influence your mind; please mind the gap between biology and mood.

What you will learn

FOUNDATION
