Bibliometric data underpinning the citation-based metrics employed in the ranking were collected on 2024-11-27. The core criterion for determining an institution's position in the ranking is the cumulative D-index (Discipline H-index) of all qualifying scholars affiliated with that institution whose principal research area is Neuroscience. Notably, the D-index captures exclusively the publications and citation metrics germane to the discipline in question, thereby ensuring an accurate and focused reflection of research prowess in Neuroscience.
Scope of Research and Data Inclusion Criteria
This edition’s ranking encompasses an exhaustive examination of 279,971 scientist profiles, identified through a range of bibliometric sources. Of these, 30,400 profiles correspond specifically to scholars in Neuroscience and were subject to in-depth analysis. The principal qualification for inclusion required that each scientist have a D-index of at least 30, alongside a publication portfolio with a majority of works in Neuroscience.
Additionally, a dynamic D-index threshold—incremented in steps of 10 relative to the discipline’s total researcher count—was set to ensure that the top 1% of influential researchers per discipline were effectively recognized. Further, for a scholar’s inclusion, the proximity between their overall H-index and D-index was required to be 30% or less, ensuring specialization within the discipline. Awards and notable achievements in Neuroscience also played a supporting role in the evaluation process, spotlighting outstanding contributions and peer recognition within the field.
Verification Practices and Data Integrity
Recognizing the limitations inherent in bibliometric data, the Research.com team employed rigorous verification protocols to uphold the reliability of the ranking. Every scientist profile underwent manual verification, complemented by cross-correlation against publication records from a broad spectrum of trusted sources. While the volume of papers in prominent journals and conferences is not a direct ranking factor, it is acknowledged as a meaningful secondary indicator of a scholar’s scientific impact.
Final positions in the ranking for each researcher were determined based on their H-index, as provided by OpenAlex and CrossRef—two of the most authoritative bibliometric databases accessible to the international research community. This multifaceted and diligent approach ensures that the ranking is both comprehensive and credible.
