The 10 most cited neuroscience papers

ResearchBlogging.org
Over on Quora someone asked, "What are the most-cited works in neuroscience?"

As some of you may know, I love literature mining. I started brainSCANr with my wife to look at how neuroscience research is conducted. I've been talking with Neuroskeptic about looking at biases in how different neuroscience topics are studied.

This question on Quora piqued my interest, so I decided to try and work out the answer. I had to do some digging.

My first thought was of a retrospective published in Nature Reviews Neuroscience last year that revisited ten of its most-cited papers between 2000 and 2010: Ten years of Nature Reviews Neuroscience: insights from the highly cited.

A quick Google search showed that the Journal of Neuroscience also has a list of its most-cited papers on its site.

But in both of these cases we've got a clear bias: they only show the highly-cited articles published within their respective journals. And there are a lot of journals that publish neuroscience research.

Any answer I can find will come with a lot of caveats. It's difficult enough to define which papers are "neuroscience", let alone track down the "top cited" ones in an unbiased manner. From what I've seen, the most-cited papers tend to be methodological or crystallography structures. However, in order to reduce any sub-field bias, I wanted to find a database of papers to work from.

The ISI Web of Knowledge runs a site, ISI Highly Cited, wherein you can search by specific neuroscience researcher, but that information doesn't tell you about specific highly-cited papers. Cool, but no good here.

Thomson Reuters (who owns the Institute for Scientific Information (ISI)) also runs ProCite, which, thankfully, has a nice little site wherein they provide citation counts for 2610 neuroscience papers published in the ten-year period between 1995 and 2005. Those data come in a nicely-formatted text file.

Yay datas!

These types of files are data pornography for me. They make what I do so easy and fun!

(Yeah, I said it. Fun. What?)

Mind you, the results from ProCite come with caveats: I can't say that they're comprehensive (I don't know how they defined "neuroscience") and they're temporally restricted (1995-2005). Never the less, it's a good start.

Of those 2610 "highly cited" articles, 1877 had more than 100 citations. 1951 of the 2610 articles were classified as "research articles", 656 as "reviews" (and 3 as "notes"?) There were a total of 108 unique journals represented in this sample.

The breakdown by of the 20 journals with the largest number of highly-cited articles looks like this:

Bradley Voytek Neuron PNAS citations

(Why yes, I do have a first-authored paper in three of those top five journals! I hadn't noticed! What? You'd like to give me a job? Why thank you! That would be delightful. ::COUGH::)

As an aside, I'd like to point out that 4 of the top 10 journals have one-word journal titles: Neuron, Nature, Science, and Neurology. Out of the 108 total journals represented, 22 have one-word titles. This means we should only see two--not four--one-word title journals in the top 10. This supports my pet theory that one-word title journals fare better than journals with longer titles. (This is a little ironic, because the journal with the longest title is also in the top 10: Proceedings of the National Academy of Sciences of the United States of America, but they've long since learned to refer to themselves simply as "PNAS".)

Of course, the earlier the year of the paper's publication, the more frequently it's been cited, which suggests that the citation counts for these articles will continue to increase (that is, after 10 years they still haven't really stopped getting cited).

Bradley Voytek citations

Without further ado, here are the 10 most highly-cited neuroscience articles published between 1995 and 2005, ordered by number of citations:

1. (1684 citations) Sherrington et al., Cloning of a gene bearing missense mutations in early-onset familial Alzheimer's disease. Nature 1995.
2. (1603 citations) Polymeropoulos et al., Mutation in the alpha-synuclein gene identified in families with Parkinson's disease. Science 1997.
3. (1513 citations) Caterina et al., The capsaicin receptor: a heat-activated ion channel in the pain pathway. Nature 1997.
4. (1396 citations) Südhof, The synaptic vesicle cycle: a cascade of protein-protein interactions. Nature 1995.
5. (1369 citations) Pin & Duvoisin, The metabotropic glutamate receptors: structure and functions. Neuropharmacology 1995.
6. (1288 citations) Tessier-Lavigne & Goodman, The molecular biology of axon guidance. Science 1996.
7. (1246 citations) McKeith et al., Consensus guidelines for the clinical and pathologic diagnosis of dementia with Lewy bodies (DLB): report of the consortium on DLB international workshop. Neurology 1996.
8. (1186 citations) Games et al., Alzheimer-type neuropathology in transgenic mice overexpressing V717F beta-amyloid precursor protein. Nature 1995.
9. (1065 citations) Hsiao et al., Correlative memory deficits, Abeta elevation, and amyloid plaques in transgenic mice. Science 1996.
10. (1050 citations) Levy-Lahad et al., Candidate gene for the chromosome 1 familial Alzheimer's disease locus. Science 1995.

What's amazing to me is that 7 of the top ten papers are from Nature or Science, and 5 of them are more or less about Alzheimer's disease. This suggests a relative homogeneity of "top" researched topics.

As a final note, it's important to point out that these publications are from 1995-2005. They ignore older papers, as well as more recent ones. Given that the modern scientific publishing era began in 2003 with the founding of PloS and PLoS Biology, there wasn't really any time for papers published in those journals to really have any representation in this dataset.
