Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in ...
Fortrea primate-testing lab, Vienna, Virginia, 2004–05. Most of the NHPs used are one of three species of macaques, accounting for 79% of all primates used in research in the UK, and 63% of all federally funded research grants for projects using primates in the U.S. [25] Lesser numbers of marmosets, tamarins, spider monkeys, owl monkeys, vervet monkeys, squirrel monkeys, and baboons are used ...
Rodents have been employed in biomedical experimentation from the 1650s. [1] Rodent studies up to the early 19th century were mainly physiological or toxicological.The first rodent behavioral study was carried out in 1822, a purely observational study [2], while quantitative rodent behavioral testing began in the late 19th century [1] [2].
Most animal testing involves invertebrates, especially Drosophila melanogaster, a fruit fly, and Caenorhabditis elegans, a nematode. These animals offer scientists many advantages over vertebrates, including their short life cycle, simple anatomy and the ease with which large numbers of individuals may be studied.
A radial arm maze allowing animals to choose between 8 variants (e.g. food) that would be placed at the end of each arm. A preference test is an experiment in which animals are allowed free access to multiple environments which differ in one or more ways. Various aspects of the animal's behaviour can be measured with respect to the alternative ...
Animal Welfare Act 1999: No person may carry out any research, testing, or teaching involving the use of a non-human hominid unless such use has first been approved by the Director-General and the research, testing, or teaching is carried out in accordance with any conditions imposed by the Director-General.
Almost all of the article deals with vertebrates, despite the large majority of animal experiments being experiments on invertebrates. Why is that? Tim Vickers 02:20, 21 August 20
Frogs have been used in animal tests throughout the history of biomedical science. Eighteenth-century biologist Luigi Galvani discovered the link between electricity and the nervous system through studying frogs .
