A researcher’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that evaluates only the subset of scientific publications and their citations within the examined discipline — Neuroscience in this case. This discipline-specific focus helps to capture a researcher’s true influence and productivity in their specialized field rather than across unrelated areas.
Scope of Research and Qualification Criteria
To develop the ranking, an extensive review was conducted of 279,971 scientist profiles aggregated across all scientific disciplines, sourced from diverse bibliometric data providers. Within this corpus, 83 scientists specializing in Neuroscience were identified and analyzed rigorously.
Eligibility for inclusion in the Neuroscience ranking required researchers to have a D-index of at least 30. Additionally, most of their top-tier publications needed to predominantly focus on Neuroscience to ensure discipline relevance. Recognizing that quantitative metrics alone may not capture the full scope of scholarly achievement, scientists’ awards and notable achievements within Neuroscience were also considered during the evaluation process.
The threshold for the D-index is calibrated adaptively based on the estimated total number of scholars in each discipline. It is incremented in steps of 10 to maintain the inclusion of the top 1% of leading researchers within each field. Furthermore, the ranking ensures an alignment between a scientist’s general H-index and their D-index, requiring that the general H-index is within 30% proximity or less to their discipline-specific score.
Verification and Validation Practices
Our research team acknowledges that raw bibliometric data, by itself, cannot serve as an absolute measure of scholarly output and impact. Therefore, every scientist profile featured in the ranking underwent thorough manual verification. Profiles were cross-validated against publications listed in a multitude of trustworthy and authoritative sources to ensure accuracy and integrity.
While not a formal component of the ranking metric, the volume of papers published in prominent journals and conference proceedings provides valuable secondary insight into a scientist’s contribution to Neuroscience. This complementary information helps contextualize the researcher’s influence beyond citation counts.
The ranking’s final positions rely exclusively on each researcher’s D-index, derived from data aggregated by OpenAlex and CrossRef—two of the most prominent and widely recognized bibliometric databases accessible to the research community.
