Forced swim test with ICV injection
From 2021 to 2025, 58 animal research papers mentioned ICV injection and the forced swim test in their title or abstract.
That is 36% fewer than the 91 papers of 2011 to 2015. Between the same two periods, the papers that mention ICV injection and any of the 90 tests we count fell 6%. The 2021 to 2025 count may run low because of a dip in PubMed's indexing, explained under the year chart.

Papers that mention ICV injection and the forced swim test fell from 12 in 2021 to 8 in 2023, then rose to 11 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 58 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

Tests mentioned alongside the forced swim test
Each bar is one test, with how many of the 58 papers also mention it, and what share that is. Of these papers, 12 (21%) mention no other test.

Which papers count
A paper counts here when it is animal research and its title or abstract mentions ICV injection and the forced swim test.
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.
