Rodents are small mammals capable of learning, displaying complex behaviors, and are relatively inexpensive to raise. They are an ideal animal to use for the study of memory. The assessment of learning and memory in rodents has been employed in scientific research for a long time, and there are many experimental methods used.
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 ...
It is also used by neuroscientists to determine whether there is a causative effect after mild traumatic brain injury on learning deficits (acquisition trials) and spatial memory retention (probe) at acute [4] and chronic time points. [5]
Laboratory rats are frequently subject to dissection or microdialysis to study internal effects on organs and the brain, such as for cancer or pharmacological research. Laboratory rats not sacrificed may be euthanized or, in some cases, become pets. Deprivation of REM sleep using the flowerpot technique
Cervical dislocation (breaking the neck or spine) may be used for birds, mice, rats, and rabbits depending on the size and weight of the animal. [187] High-intensity microwave irradiation of the brain can preserve brain tissue and induce death in less than 1 second, but this is currently only used on rodents.
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. [3] Rats such as the bandicoot rat (Bandicota bengalensis) are murine rodents related to true rats but are not members of the genus Rattus ...
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 ...
