Bibliometric Analysis of Neurotransmitter-Mediated Gut-Brain Axis Research, 2005-2025

788 publications from Web of Science, Scopus, and PubMed were analyzed to map the evolution of research on the neurotransmitter-mediated gut-brain axis. The study, authored by Ziyi Guo and uploaded in 2026, identifies three developmental phases and leading contributors like John F. Cryan. Core topics include gut microbiota, serotonin, and implications for disorders like depression and inflammatory bowel disease.

Use Cases

• Identify leading authors and institutions based on publication and citation counts mentioned in the results.
• Analyze keyword evolution and thematic shifts from mechanistic to disease-specific research as described.
• Map international collaboration networks based on the geographic distribution of publications.
• Study publication growth trends across the identified exploratory, developmental, and rapid expansion phases.

Strengths

• Analysis is based on 788 publications from three major databases (Web of Science, Scopus, PubMed).
• Provides specific citation metrics, such as University College Cork's 10,935 citations from 28 publications.
• Covers a defined 20-year time range from 2005 to 2025.

Limitations

• The dataset is a 14.9 KB DOCX file, indicating a very limited textual summary rather than the underlying raw bibliographic data.
• Column-level documentation for any underlying data tables is absent; field semantics must be inferred after download.
• Row count for any potential tabular data within the document is unknown.
