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.

Environmental effects on animals used in biomedical research

The intensity of light in animal cages is likely to be the most variable environmental factor in the average animal room. p 512Of 250 articles only 32% report details on caging, 11% on bedding material, 42% on lighting and 0%...

Social housing of rats: Life-span effects on reaction time, exploration, weight, and longevity

Sprague-Dawley rats were housed throughout their lives either in group cages or singly in standard laboratory cages. Locomotor activity was observed at selected ages and, in addition, operant conditioning procedures were used with an extensively trained subset of the animals...

The effect of conspecifics on corticoadrenal response of rats to a novel environment

The effect of housing conditions and the presence of a conspecific on corticoadrenal response to a novel environment was studied in male Sprague-Dawley rats. The response to a novel environment was the same in rats housed in groups and rats...
