Influence of environment structure and food availability on the foraging behaviour of the laboratory rat

We suggest that foraging decisions depend primarily on safety needs, rather than food availability, at least when animals are not severely food-deprived.

Disruptive effects of standard husbandry practice on laboratory rat social discrimination

It appears that when rats are first grouped, they should be undisturbed for a least 24 h to prevent possible recognition failure as a result of exposure to handling or to the odours of novel conspecifics.

Chronic stress and social housing differentially affect neurogenesis in male and female rats

Stress plays an important role in the development of affective disorders. Women show a higher prevalence for these disorders than men. The course of a depression is thought to be positively influenced by social support. We have used a chronic...

Environmental enrichment: Beneficial effects in a rodent model of lead neurotoxicity

Using a rodent model of lead-induced neurotoxicity, we show that environmental enrichment reverses cognitive and molecular deficits induced by this developmental neurotoxicant... At weaning, pups were removed from the lead exposure and housed in isolation or environmental enrichment cages (8...

Do laboratory rats benefit from more cage space?

The porphyrin scores were significantly higher in rats housed in small or large cages that were barren than in rats housed in small or large cages that were furnished with a PVC tube. The lowest porphyrin scores were found in...

Environmental enrichment affects striatal graft morphology and functional recovery
