Environmental Enrichment

Enrichment slows disease progression in R6/2 Huntington?s disease mice

Housing mice in standard laboratory cages increased the rate of disease progression while housing them in enriched cages slowed the progress to a more 'normal' rate. Mice housed in such deprived conditions are unlikely to prove a good model of...

Future improvements and implementation of animal care practices within the animal testing regulatory environment

The enrichment of the animals' environment will not likely affect the interpretation of the results, particularly if adequate controls are used. Appropriate enrichment methods can be chosen to be compatible with the aims of the study [p. 82].

Environmental enrichment decreases intravenous amphetamineself-administration in rats: dose-response functions for fixed- andprogressive-ratio schedules

This result suggests that environmental enrichment may be a protective factor for reducing amphetamine intake at a low dose.

Environmental influences on functional outcome after a cortical infarct in the rat

We conclude that the beneficial effect of postischemic environmental enrichment is likely to be a combination of social and various physical activities.

Environmental enrichment for rats

My personal research has shown that as colony-dwelling animals, rats require contact with their own kind; as small burrowing animals they want a secure nest-box more than a novel object to investigate; as a prey species they prefer cages that...

Improving housing conditions for laboratory mice: A review of ‘environmental enrichment’

We have reviewed 40 studies carried out between 1987 and 2000, in which preferences as well as the effect of housing modifications have been studied. Mice will work for access to nesting material and make use of this material to...

Impact of environmental enrichment in mice

Animals at 3 weeks of age were marked and separated randomly to enriched or non-enriched cages, in groups of four, half for each housing condition. Both cages were type III Makrolon cages, only the enriched cages contained a nest box,...
