Environmental Enrichment

Potential for unintended consequences of environmental enrihment for laboratory animals and research results

Many aspects of the research animal's housing environment are controlled for quality and/or standardization. Of recent interest is the potential for environmental enrichment to have unexpected consequences such as unintended harm to the animal, or the introduction of variability into...

New neurons in the dentate gyrus are involved in the expression of enhanced long-term memory following environmental enrichment

Although thousands of new neurons are continuously produced in the dentate gyrus of rodents each day, the function of these newborn cells remains unclear. An increasing number of reports have provided correlational evidence that adult hippocampal neurogenesis is involved in...

Building a novel environment for a feline enrichment program

We believe the addition of the colony [group] cage has led to friendlier and more well-adpated cats. .. Two groups are rotated weekly between the large colony cage and individual caging.

Anticipatory behavior – A new indicator of the significance of environmental enrichment in laboratory-housed common marmosets

It was suggested that anticipatory behavior is a useful method for assessing the value of feeding enrichment options.

Environmental enrichment for laboratory rodents and rabbits: Requirements of rodents, rabbits, and research

Environmental conditions such as housing and husbandry have a major impact on the laboratory animal throughout its life and will thereby influence the outcome of animal experiments. However, housing systems for laboratory animals have often been designed on the basis...

Modifying the behaviour of singly caged baboons: evaluating the effectiveness of four enrichment techniques

Seven singly caged adolescent [mean age: 4.2 years] male baboons were studied. Analysis of baseline behaviour verified substantial durations of abnormal behaviour [9.8/30- min observations (33% of time)]. We tested the effectiveness of ... positive reinforcement training (PRT), food enrichment...

Mandatory enriched housing of laboratory animals: The need for evidence-based evaluation

Environmental enrichment for laboratory animals has come to be viewed as a potential method for improving animal well-being in addition to its original sense as a paradigm for learning how experience molds the brain. It is suggested that the term...
