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...

Providing shelter does not complicate manipulation in two mouse strains

Enrichment in the form of sheltering objects [PVC tubes] does not complicate catching or handling mice and does not interfere with management or cost of laboratory animals. FVB males should not be kept together unless such enrichment is provided.

To enrich or not to enrich: providing shelter does not complicate handling of laboratory mice

It is argued that when laboratory mice can routinely retreat in sheltering objects when humans are present, they do not habituate to humans and continue to shy away, thereby increasing the time needed for husbandry and testing procedures. ... We...

Enriched environment influences adrenocortical response to immune challenge and glutamate receptor gene expression in rat hippocampus

The purpose of this study was to evaluate whether enriched rearingcould alter the stress response induced by repeated immune challenge and to investigate the influence of EE [environmental enrichment] and immune challenge on glutamate receptor gene expression in the hippocampus....

Effect of environmental enrichment on stress related systems in rats

Environmental enrichment leads to pronounced changes in neuroendocrine regulation, including larger adrenals and increased adrenocortical function, which are so far considered to be indication of chronic stress.Animal living in groups of 10 in enriched cages had higher resting corticosterone concentrations...

Refinement of routine procedures: Can environmental enrichment reduce the stress response of laboratory mice

Female mice housed in trios in enriched cages and handled daily reacted with less anxiety to procedures than female mice housed singly in barren cages and handled only when necessary.
