Streptozotocin in the brain (ICV-STZ)

From 2021 to 2025, 174 animal research papers mentioned streptozotocin in the brain (ICV-STZ) and at least one behavioral test.

That is 2.3 times the 76 papers of 2011 to 2015. Between the same two periods, all the animal research papers that mention any of the 90 tests we count grew more slowly, to 1.2 times as many.

2.3 times as many papers as in 2011 to 2015
65% of these papers mention the Morris water maze
61% of the 286 animal research papers from 2021 to 2025 that mention streptozotocin in the brain (ICV-STZ) also mention a test

The tests mentioned with streptozotocin in the brain (ICV-STZ)

Passive avoidance appears in 25% of these papers and in 3.5% of all 32,277 papers that mention a test. That makes it 7.0 times as common in this research. Each bar is one test, with how many of the 174 papers from 2021 to 2025 mention it, and what share that is. A paper that mentions two tests counts under both.

Papers that mention streptozotocin in the brain (ICV-STZ) and a test fell from 29 in 2021 to 26 in 2023, then rose to 45 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.

Disease models in papers that mention streptozotocin in the brain (ICV-STZ)

Each bar is one disease model, with how many of the 174 papers from 2021 to 2025 are tagged with it, and what share that is. The model comes from the paper's MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. A paper without MeSH terms gets its model from PubTator 3, NCBI's text-mining service, if PubTator 3 finds the disease in the title or abstract. A paper can count under more than one model.

Which species the papers used

Each bar is a share of the 174 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.

NIH funding

4 of the 174 papers (2%) had NIH funding. NIAAA, the National Institute on Alcohol Abuse and Alcoholism, funded the most, 3 of them. A paper counts as NIH-funded when its PubMed record lists an NIH grant, or when NIH RePORTER links it to an NIH project.

Each share is of the NIH-funded papers. A paper with grants from two institutes counts under both.

How we counted

A paper counts here when it is animal research and its title or abstract mentions streptozotocin in the brain (ICV-STZ) and at least one of the 90 behavioral tests. A count is a number of papers, not of experiments, labs or animals. A paper that mentions streptozotocin in the brain (ICV-STZ) only in its methods is missed, so the count runs low.

A paper is animal research when its MeSH terms name an animal species. If they name none, NCBI's text-mining service PubTator 3 has to find one in the title or abstract. Papers on animals other than mice, rats, zebrafish, flies and primates count only when they also mention a test. Many of them study people or use the same words for something else.

The search terms for streptozotocin in the brain (ICV-STZ) are in the download Animal models and brain techniques. The counts in the chart of tests are in Tests mentioned with each model or technique. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.

More animal models

Each animal model with 100 or more papers from 2021 to 2025 that mention a test has a page. These are the others, each with that count.
