Fear conditioning with in vivo electrophysiology

From 2021 to 2025, 40 animal research papers mentioned in vivo electrophysiology and fear conditioning in their title or abstract.

That is 1.3 times the 30 papers of 2011 to 2015. Between the same two periods, the papers that mention in vivo electrophysiology and any of the 90 tests we count grew faster, to 1.9 times as many.

Papers that mention in vivo electrophysiology and fear conditioning fell from 10 in 2021 to 4 in 2022, then rose to 10 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 40 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 40 papers also mention it, and what share that is. Of these papers, 27 (68%) mention no other test.

Which papers count

A paper counts here when it is animal research and its title or abstract mentions in vivo electrophysiology 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.

Other tests with in vivo electrophysiology

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