Fear conditioning in Alzheimer disease research
From 2021 to 2025, 125 animal research papers on Alzheimer disease mentioned fear conditioning in their title or abstract.
That is 2.0 times the 63 papers of 2011 to 2015. Between the same two periods, the papers on Alzheimer disease that mention any of the 90 tests we count grew faster, to 2.8 times as many.

Papers on Alzheimer disease that mention fear conditioning fell from 29 in 2021 to 19 in 2023, then rose to 21 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. Where PubMed has indexed a paper, we take its disease models from that indexing. Otherwise PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract, or the paper is not counted here. Papers that PubMed indexed under the subject heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025.
Which species the papers used
Each bar is a share of the 125 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 fear conditioning
Each bar is one test, with how many of the 125 papers also mention it, and what share that is. Of these papers, 52 (42%) mention no other test.

Which papers count
A paper counts here when it is animal research, mentions fear conditioning in its title or abstract, and studies Alzheimer disease.
We tell whether a paper studies Alzheimer disease 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 Alzheimer disease research names the subject headings we count as Alzheimer disease. Download the test list for the search terms we used for fear conditioning, 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.
