Fear conditioning with chemogenetics

From 2021 to 2025, 78 animal research papers mentioned chemogenetics and fear conditioning in their title or abstract.

There were 4 such papers in 2011 to 2015. We compare the two periods only when each has 10 or more papers.

78 animal research papers from 2021 to 2025 mentioned chemogenetics and fear conditioning
15% of the 505 papers from 2021 to 2025 that mention chemogenetics and a test mention fear conditioning
4% of the 2,010 papers from 2021 to 2025 that mention fear conditioning also mention chemogenetics
4 papers in 2011 to 2015, fewer than the 10 needed to compare

Papers that mention chemogenetics and fear conditioning fell from 13 in 2021 to 9 in 2022, then rose to 21 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. We take a paper's species from PubMed's indexing when the indexing names one. Otherwise PubTator 3, NCBI's text-mining service, has to find a species in the title or abstract, or the paper is not counted. 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 78 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

“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 78 papers also mention it, and what share that is. Of these papers, 63 (81%) mention no other test.

Which papers count

A paper counts here when it is animal research and its title or abstract mentions chemogenetics and fear conditioning.

A paper that mentions either only in its methods is missed, so the count runs low. The search terms are in the list of models and techniques and the test list. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.

More pairings

Every pairing of a brain technique and a test with 30 or more papers from 2021 to 2025 has a page like this one.

The page on fear conditioning counts all the papers that mention it, whatever they study. The page on chemogenetics ranks the tests mentioned with it.
