Open field in cognitive impairment and dementia research
From 2021 to 2025, 493 animal research papers on cognitive impairment and dementia mentioned the open field in their title or abstract.
That is 3.3 times the 149 papers of 2011 to 2015. Between the same two periods, the papers on cognitive impairment and dementia that mention any of the 90 tests we count grew more slowly, to 1.7 times as many.

Which species the papers used
Each bar is a share of the 493 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.
Species
“Other animals” counts papers that use none of the species this chart names.
Tests mentioned alongside the open field
Each bar is one test, with how many of the 493 papers also mention it, and what share that is. Of these papers, 24 (5%) mention no other test.

Which papers count
A paper counts here when it is animal research, mentions the open field in its title or abstract, and studies cognitive impairment and dementia.
We tell whether a paper studies cognitive impairment and dementia from its MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. For a paper without MeSH terms, PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract. A paper can count under more than one disease model. A paper that mentions the test only in its methods is missed, so the count runs low.
The page on cognitive impairment and dementia research names the subject headings we count as cognitive impairment and dementia. Download the test list for the search terms we used for the open field, or the paper list for the PubMed ID of every paper behind these counts. Our main page, Behavioral tests in published research, has the full method and each source's terms of use.
