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 ...
The test can detect antipsychotic-like activity both in the case of dopamine D 2 receptor antagonists and in the case of drugs lacking D 2 receptor antagonism. [1] [2] [6] The occupancy of the D 2 receptor by antagonists of this receptor required to inhibit the CAR is around 65 to 80%, which is similar to the occupancy at which therapeutic antipsychotic effects occur in humans with these drugs.
In 1954, the Universities Federation for Animal Welfare (UFAW) decided to sponsor systematic research on the progress of humane techniques in the laboratory. [2] In October of that year, William Russell, described as a brilliant young zoologist who happened to be also a psychologist and a classical scholar, and Rex Burch, a microbiologist, were appointed to inaugurate a systematic study of ...
Between 90% and 95% of drugs that pass animal testing fail in human trials, which can take up to 15 years and cost between $1 billion and $6 billion, according to a news release from the Animal ...
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 ...
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].

The Monkey Drug Trials of 1969 were a series of controversial animal testing experiments that were conducted on primates to study the effects of various psychoactive substances. The trials shed light on the profound effects of drug addiction and withdrawal in primates, pioneering critical insights into human substance abuse. [1]
