Learned helplessness
From 2021 to 2025, 85 animal research papers mentioned learned helplessness in their title or abstract, ranking it 60th of the 90 tests we track.
That is 33% fewer than the 126 papers of 2011 to 2015. Papers that mention any of the 90 tests rose 22% over the same span.

Which species the papers used
Each bar is a share of the 85 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 other species in this chart.
Strains and genetic lines
Strain names come from the MeSH terms PubMed adds when it indexes a paper. PubMed has indexed 71 of the 85 papers, so each bar is a share of those 71.
A paper indexed under two of these headings, such as knockout mice and a strain, counts under both.
Disease models these papers study
Each bar counts the papers from 2021 to 2025 that mention learned helplessness and study that disease model, with its share of the 85 papers. The model comes from a paper's MeSH terms. For a paper PubMed has not indexed, it comes from PubTator 3, NCBI's text-mining service, when that service finds the disease in the title or abstract. A paper can count under more than one model.

Tests mentioned alongside learned helplessness
Each bar counts the papers from 2021 to 2025 that mention both tests, with its share of the 85 papers that mention learned helplessness.

The most cited papers from 2021 to 2025
These papers from 2021 to 2025 mention learned helplessness and have the most citations, as counted by NIH's iCite on November 5, 2026. We show four of the five most cited papers and leave out one because of words in its title.
Sex differences in anxiety and depression: circuits and mechanisms.
Nat Rev Neurosci, 2021. 383 citations.
Animal Models of Depression: What Can They Teach Us about the Human Disease?
Diagnostics (Basel), 2021. 136 citations.
Dopamine pathways mediating affective state transitions after sleep loss.
Neuron, 2024. 72 citations.
Transl Psychiatry, 2023. 64 citations.
How we counted
A count is the number of animal research papers whose title or abstract mentions one of the test's search terms. It is not a count of experiments, labs or animals.
A paper that mentions learned helplessness only in its methods is missed, so the count runs low. The count includes 4 reviews. For 14 of the 85 papers, PubMed's indexing gave no species, so the species came from PubTator 3 finding one in the title or abstract.
The test's search terms are in the test list download. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.
More depression-like behavior tests
These depression-like behavior tests also have a page, with their papers from 2021 to 2025. Each test with 30 or more papers gets one.
