Age at group formation alters behavior and physiology in male but not female CD-1 mice

In the laboratory environment, rodents are usually housed in unisexual groups, which are assembled after weaning. Housing of unfamiliar subjects has been described, however, as a stressful social setting for rodents and other mammals. Aim of the present study was...

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...

Foraging enrichment for laboratory rats

The limited-access hopper had a tendency to reduce food consumption, but the time spent feeding encreased. The gnawing sticks provided the rats with the opportunity to gnaw, but did not affect other behaviours or body weight. The foraging device had...

Environmental enrichment affects striatal graft morphology and functional recovery

Here we report on the effects of differential housing conditions on striatal graft morphology and functional recovery after striatal lesions... An increased level of striatal brain-derived neurotrophic factor was observed in the control animals housed under the enriched compared with...

Behavioural and welfare benefits using environmental enrichment for social housed rats

Constructing their own nests not only allowed the rats to engage in a species-typical behavior, which presumably enhanced their feeling of security, but it also reduced the incident of aggressive interactions.

Social facilitation of wound healing

It is well documented that psychological stress impairs wound healing in humans and rodents. However, most research effort into influences on wound healing has focused on factors that compromise, rather than promote, healing. In the present study, we determined if...

Common variations in the pretest environment influence genotypic comparisons in models of anxiety

To this end, the inbred rat strains Lewis (LEW) and spontaneously hypertensive rats (SHR), which are known to differ for numerous emotionality-related behaviors, were tested in the open field (OF), elevated plus maze (EPM) and black/white box (BWB), while three...
