Effects of environmental enrichment on old mice

Groups of 3 or 4 male mice were transferred to 45x17x15 cm large caged containing structures to crawl through, marbles, ping pong balls plus 4 sexually receptive females. Subjects were tested when they were 750 days old. The enriched mice...

Influence of cage shelf level on retinal atrophy in mice

The correlation between cage shelf level andretinal atrophywas examined by analyzing data obtained from a chronic study carried out in 24,192 female BALB/cmice. Each cage ofanimalswas maintained on a cage rack at a given shelf level throughout the course of...

Influence of environmental rearing history and postsurgical environmental change on the septal rage syndrome in mice

The restricted mice were more reactive to handling than the enriched mice presurgically (60 days old), and interactions of housing conditions and surgery were found over the seven day postsurgical handling and testing period. The restricted mice given septal lesions...

Sound and its significance for laboratory animals

Several methods of varying accuracy have been used to assess what sounds small laboratory animals such as rodents are capable of hearing. Most rodents can detect sounds from 1000 Hz (the frequency of the Greenwich Time Signal) up to 100000...

Environmental enrichment and restriction: Effects on reactivity, exploration and maze learning in mice with septal lesions

Mice from enriched living conditions showed less fear responses [resistance to capture, handling; vocalization] than mice from barren standard housing conditions.
