A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator which considers only the publications and citations pertinent to the specific discipline under examination—in this case, Neuroscience. This ensures that the ranking reflects a researcher’s impact and productivity within their specialized field rather than general scholarly influence.
Scope of Research and Inclusion Criteria
The ranking’s scope was established through a rigorous examination of 279,971 scientist profiles initially identified from a diverse array of bibliometric data sources spanning all academic disciplines. Within this corpus, five scientists specializing in Neuroscience from South Africa were evaluated for inclusion.
To qualify for the Neuroscience ranking, a scientist was required to have a D-index of at least 30. Additionally, a majority of their tier publications had to be directly related to Neuroscience research. Consideration was also given to researchers’ awards and notable achievements in the field, further supporting a qualitative dimension beyond pure metrics.
The D-index threshold is set incrementally in steps of 10 relative to the estimated total number of active scholars in each discipline. This approach is designed to include the top 1% of experts, ensuring the list reflects the leading contributors accurately. Another key criterion is that the proximity between a scientist’s general H-index and their Neuroscience-specific D-index does not exceed 30%, thereby emphasizing a focused and significant engagement with the subfield.
Verification and Methodological Rigor
We recognize that raw bibliometric data are inherently insufficient as a standalone measure of scholarly output. Consequently, all scientist profiles included in the ranking underwent thorough manual verification. This involved cross-correlation with publications catalogued across a broad spectrum of reputable sources to authenticate their contributions.
While not directly affecting the ranking position, the quantity of papers published in prominent journals and conference proceedings is considered a valuable supplementary signal of a scientist’s impact within Neuroscience.
Positions in the ranking rely exclusively on the D-index values that derive from data consolidated via OpenAlex and CrossRef, two of the most authoritative and widely-utilized bibliometric databases available to the global research community.
