Psychobiotics and the Neuro-Gastro Frontier

Psychobiotics and the Neuro-Gastro Frontier includes fourteen Chapters, intending to take readers from basic ideas to new clinical and translational applications. The first sections describe the structure and function of the gut–brain axis, developmental origins of microbiome–brain interactions, and lifestyle and environmental factors that shape microbial ecosystems. The following chapters discuss psychobiotic classifications, mechanistic pathways, neuroimmune interactions, clinical trials, safety issues, and regulatory frameworks. The purpose of this work is to synthesize up-to-date research with practical and mechanistic insights, bringing together basic neurogastroenterological science and therapeutic potential in the real world.
