Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Neuroscience Scientists in Norway Ranking is primarily based on comprehensive bibliometric data aggregated from leading academic data providers, including OpenAlex and CrossRef, supplemented by multiple additional reputable data sources. The citation-based metrics underpinning the ranking were meticulously collected on January 12, 2026, ensuring the most recent and relevant data was employed in the analysis.
A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined bibliometric measure that exclusively accounts for publications and citation impact within the examined discipline of Neuroscience. This specialization ensures that the ranking precisely reflects researchers’ contributions specifically within their field.
Scope and Criteria of the Ranking
The ranking examination encompassed a broad dataset including 279,971 scientist profiles drawn from a wide array of bibliometric databases spanning all academic disciplines. Within this comprehensive dataset, 48 scientists identified as active contributors in Neuroscience were specifically evaluated. To qualify for inclusion in the Neuroscience ranking, a researcher was required to have a D-index of at least 30, with the majority of their tier publications focused in the area of Neuroscience.
Additionally, consideration was given to scientists’ awards and recognitions pertinent to Neuroscience, providing a multi-dimensional perspective on scholarly impact. The D-index threshold for top researchers is strategically scaled by increments of 10, calibrated according to the estimated total number of scholars within each discipline, which ensures representation of approximately the top 1% of leading experts. Furthermore, the methodology requires that the gap between a researcher’s overall H-index and their discipline-specific D-index remains within 30%, guaranteeing alignment between their general and field-specific scholarly influence.
Additional Verification Practices
Recognizing the limitations of raw bibliometric data as an absolute evaluative tool, the Research.com team undertakes rigorous manual verification of all scientist profiles included in the ranking. Each profile is cross-correlated with publications indexed in a broad range of trustworthy and authoritative sources to confirm accuracy and domain relevance.
While not influencing the computed ranking positions, the number of publications a researcher has in prominent journals and reputable conference proceedings is acknowledged as a valuable secondary indicator of their contribution to the discipline. The final ranking positions are derived exclusively from each scientist’s D-index calculated using data from OpenAlex and CrossRef — two of the most prominent and widely respected bibliometric databases accessible to the research community.
