Genetic differences influencing behavioural temperature regulation in small mammals: I. Nesting by Mus musculus

When nest material is placed on the cage lid, mice will readily pull it into the cage and build a nest.

Hair-nibbling and whisker-trimming as indicators of social hierarchy in mice

Barbering is a common abnormal behavior in laboratory mice. Alopecia and loss of facial hair, as well as loss of vibrissae, seem to be a physical indiaction of social dominance.

The effects of cage environment upon avoidance responding in aged rats

The beneficial effects of environmental enrichment are not restricted to a brief cricial period in development. Positive effects occur also in rats aged 300 days when first placed in an enriched environment.

Effects of environmental enrichment and impoverishment on rat cerebral cortex

The first part of this paper deals with rat brain anatomy as affected by variations of starting age and of duration of exposure to enriched (complex) or impoverished (restricted) environmental conditions. Cerebral cortical depth measurements and weights of brain samples...

Long-term isolation stress and its effects on drug response in rodents

This review of the literature has illustrated that isolation stress, especially long-term isolation stress in rats and mice, can affect the growth, behavior, physiological condition, and response to a wide variety of drugs. ... Isolation stress in mice produces abnormal...

The effects of familiar visual and olfactory cues on the aggression behaviour of mice

Decreasing the familiarity of the environment and providing flexible avenues of escape lead to reduced levels of inter-male aggression. Greatest levels of aggression were found in cages that had ungergone incomplete cleaning, such as renewal of substrate only.

The preference of rats for free or response-produced food

The majority [but not all] of rats preferred freely available food over food that could be obtained only via lever pressing.
