Novelty-suppressed feeding in depression research

From 2021 to 2025, 146 animal research papers on depression mentioned novelty-suppressed feeding in their title or abstract.

That is 2.1 times the 69 papers of 2011 to 2015. Between the same two periods, the papers on depression that mention any of the 90 tests we count grew more slowly, to 1.5 times as many.

Papers on depression that mention novelty-suppressed feeding fell from 30 in 2021 to 24 in 2023, then rose to 26 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. Where PubMed has indexed a paper, we take its disease models from that indexing. Otherwise PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract, or the paper is not counted here. 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 146 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

Which papers count

A paper counts here when it is animal research, mentions novelty-suppressed feeding in its title or abstract, and studies depression.

We tell whether a paper studies depression from its MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. For a paper without MeSH terms, PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract. A paper can count under more than one disease model. A paper that mentions the test only in its methods is missed, so the count runs low.

The page on depression research names the subject headings we count as depression. Download the test list for the search terms we used for novelty-suppressed feeding, or the paper list for the PubMed ID of every paper behind these counts. Our main page, Behavioral tests in published research, has the full method and each source's terms of use.
