  4. Laboratory rat - Wikipedia

    en.wikipedia.org/wiki/Laboratory_rat

    Laboratory rats or lab rats are strains of the rat subspecies Rattus norvegicus domestica (Domestic Norwegian rat) which are bred and kept for scientific research. While less commonly used for research than laboratory mice, rats have served as an important animal model for research in psychology and biomedical science. [1]

  5. Animal testing on rodents - Wikipedia

    en.wikipedia.org/wiki/Animal_testing_on_rodents

    Rodents have been employed in biomedical experimentation from the 1650s. [1] Currently, rodents are commonly used in animal testing, particularly mice and rats, but also guinea pigs, hamsters, gerbils and others. Mice are the most commonly used vertebrate species, due to their availability, size, low cost, ease of handling, and fast ...

    en.wikipedia.org/wiki/Laboratory_mouse

    The Jackson Labs DO (Diversity Outbred) project [30] is a mouse breeding program using multiple inbred founder strains to create a genetically diverse population of mice for use in scientific research. These mice are designed for fine genetic mapping, and capture a large portion of the genetic diversity of the mouse genome. [31] This project ...

    The term rat is also used in the names of other small mammals that are not true rats. Examples include the North American pack rats (aka wood rats [3]) and a number of species loosely called kangaroo rats.

  9. Torpor - Wikipedia

    en.wikipedia.org/wiki/Torpor

    Slowing metabolic rate to conserve energy in times of insufficient resources is the primarily noted purpose of torpor. [18] This conclusion is largely based on laboratory studies where torpor was observed to follow food deprivation. [19] There is evidence for other adaptive functions of torpor where animals are observed in natural contexts:
