The bibliometric data utilized for devising the citation-based metrics underpinning the ranking were collected on January 12, 2026. This snapshot provides a robust and current foundation to assess scientific output and impact as reflected through citation dynamics at the time of analysis. A scientist's position in the ranking is determined by their Discipline H-index (D-index), which is a refined citation metric accounting exclusively for publications and citations pertinent to the specific discipline under examination—in this case, Neuroscience.
Scope of Research and Inclusion Criteria
Our methodology began with the examination of a broad set of 279,971 scientist profiles identified from a diverse array of bibliometric sources, spanning all scientific disciplines. From this extensive pool, 34 scientists specializing in Neuroscience based in New Zealand were analytically assessed for inclusion in the current ranking.
To qualify for the ranking, a scientist’s D-index had to meet a threshold of at least 30, ensuring significant disciplinary impact. Additionally, a majority of each qualifying scientist’s tier publications were required to be within the domain of Neuroscience, reflecting focused expertise. Recognized awards and professional achievements within Neuroscience further informed the assessment process.
The D-index thresholds are set dynamically as increments of 10, calibrated according to the estimated total number of scholars within each discipline. This approach guarantees inclusion of the top 1% of leading scholars, while maintaining scientific rigor. Furthermore, to ensure disciplinary relevance and consistency, a proximity criterion was applied where the difference between a scientist’s overall H-index and their Neuroscience-specific D-index did not exceed 30%.
Verification and Validation Practices
The Research.com team acknowledges that raw bibliometric data alone cannot provide a fully definitive evaluation of a researcher’s output or influence. Therefore, all scientist profiles included in the ranking undergo manual verification. This process involves cross-correlating profile information and performance metrics against publications verified from a wide range of authoritative and trustworthy scientific sources.
While not directly influencing a scientist’s ranking position, the quantity of publications in prominent peer-reviewed journals and reputable conference proceedings remains a valuable secondary indicator of research contribution and impact within the neuroscience discipline.
The final position of each researcher in the ranking is established using the D-index, derived from data aggregated from OpenAlex and CrossRef — two of the most prominent and widely recognized bibliometric databases freely available to the global research community.
