Schizophrenia and psychosis
From 2021 to 2025, 401 animal research papers on schizophrenia and psychosis mentioned at least one behavioral test, most often prepulse inhibition and acoustic startle.
That is 9% fewer than the 443 papers of 2011 to 2015. Papers that mention any of the 90 tests rose 22% over the same span. The 2021 to 2025 count may run low because of a dip in PubMed's indexing, explained under the year chart.
The tests these papers mention
Prepulse inhibition and acoustic startle appears in 40% of the papers on schizophrenia and psychosis and in 2.5% of all 32,277 papers that mention a test. That makes it 16 times as common in this research. Each bar counts the papers from 2021 to 2025 on schizophrenia and psychosis that mention the test, with its share of the 401 papers. A paper that mentions two tests counts under both.

Papers on schizophrenia and psychosis fell from 102 in 2021 to 66 in 2024, then rose to 77 in 2025. Papers that PubMed indexed under the MeSH heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025. We take each paper's disease models from PubMed's indexing whenever PubMed has indexed the paper, so part of this dip may come from the indexing rather than from fewer studies.
Which species the papers used
Each bar is a share of the 401 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.
Which papers count
A paper counts here when it is animal research, mentions at least one of the 90 tests and studies schizophrenia and psychosis.
A paper counts under schizophrenia and psychosis when its MeSH terms, the subject headings PubMed adds when it indexes a paper, include one of these.
- Schizophrenia, with the headings under it
- Psychotic Disorders
For a paper PubMed has not indexed, PubTator 3, NCBI's text-mining service, supplies the disease model when it finds the disease in the title or abstract. A paper can count under more than one disease model.
Each paper and its disease models are in the downloads. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.
