Environmental enrichment enhances auditory takeover of the occipital cortex in anophthalmic mice

Enrichment of the environment is an effective means of enhancing neuronal development and plasticity but its effect on the cross-modal compensation resulting from sensory deprivation has never been investigated. The present study used c-Fos immunohistochemistry and dextran-biotin neuronal tracing to...

Long-term effects of the periadolescent environment on exploratory activity and aggressive behaviour in mice: social versus physical enrichment

The aims of the present study were (i) to investigate the effects of environmental enrichment during periadolescence on different behavioural and neurochemical responses in male CD-1 mice at adulthood and (ii) to describe the relative role of the physical and...

Utilisation of a physically-enriched environment by laboratory mice: age and gender differences

The aim of the present study was to evaluate the age and sex differences in the utilisation of a physically-enriched environment, consisting of four differently-shaped plastic compartments: a central chamber, a circle, a running wheel and a tower.... Presence and...

Impact of group housing on post-operative recovery in mice

Results of the open-field test after two weeks of recovery in group- or single-housed conditions showed significant [unspecified] changes in locomotion and rearing.

Cage enrichment and mouse behaviour

Mice housed in standard cages show impaired brain development, abnormal repetitive behaviours (stereotypies) and an anxious behavioural profile, all of which can be lessened by making the cage environment more stimulating. But concerns have been raised that enriched housing might...

Novel mouse housing system

Keeping mice in interconnected double cages reduced the chance of animals escaping since the cage does not need to be openend during changing. It also provided enrichment by allowing the mice to move about cages more freely.

Preference for social contact versus environmental enrichment in male laboratory mice

Results indicated that when other conditions were similar, male mice preferred to sleep in close proximity to their familiar cage mate. Furthermore, the need to engage in active social behaviour increased with age. Tissues were used to a large extent...

Long-term effects of husbandry procedures on stress-related parameters in male mice of two strains

Long-term provision of nesting material and its transfer during cage cleaning was found to influence several stress-related physiological parameters. Mice housed in cages enriched with nesting material had lower urine corticosterone levels and heavier thymuses, and they consumed less food...

Short-term effects of a disturbed light-dark cycle and environmental enrichment on aggression and stress-related parameters in male mice

This experiment has shown that disturbed lighting for socially-housed male mice caused physiological and behavioural changes indicative of not only leading to much higher levels of corticosterone [via urine collection] but also to shorter agonistic within the groups. .. No...
