Environmental Enrichment

Effects of enriched housing on the neuronal morphology of mice that lack zinc transporter 3 (ZnT3) and vesicular zinc

In the central nervous system, certain neurons store zinc within the synaptic vesicles of their axon terminals. This vesicular zinc can then be released in an activity-dependent fashion as an intercellular signal. The functions of vesicular zinc are not entirely...

Effects of olfactory and auditory enrichment on heart rate variability in shelter dogs

Animal shelters can be stressful environments and time in care may affect individual dogs in negative ways, so it is important to try to reduce stress and arousal levels to improve welfare and chance of adoption. A key element of...

Effects of olfactory and auditory enrichment on the behaviour of shelter dogs

Shelter environments are stressful for dogs, as they must cope with many stimuli over which they have little control. This can lead to behavioural changes, negatively affect their welfare and downgrade the human‐animal bond, affecting re-homing success. Arousal is evident...

Efficient, effective, reusable, and customizable social housing for chickens in the laboratory

The Iowa State University Laboratory Animal Resources Department needed caging specifically designed and purposed to socially house chickens in the laboratory. As indoor housing requests for chickens increased, the need for a dedicated caging system for chickens became a high...

Enriched environment effect on lipopolysaccharide-induced spatial learning, memory impairment and hippocampal inflammatory cytokine levels in male rats

Neuro-inflammation is responsible for cognitive impairments and neurodegenerative diseases such as Alzheimer’s disease. In this study, we aimed to investigate the enriched environment (EE) effect on learning and memory impairment as well as on pro-inflammatory cytokines changes induced by lipopolysaccharide...

Enriched environment exposure accelerates rodent driving skills

Although rarely used, long-term behavioral training protocols provide opportunities to shape complex skills in rodent laboratory investigations that incorporate cognitive, motor, visuospatial and temporal functions to achieve desired goals. In the current study, following preliminary research establishing that rats could...

Enriched environments enhance cognition, exploratory behaviour and brain physiological functions of Sparus aurata

Environmental enrichment is considered as a recommended tool to guarantee or improve the welfare of captive fish. This study demonstrates for the first time that structural environmental enrichment enhances cognition, exploratory behaviour and brain physiological functions of gilthead seabream (Sparus...

Enrichment preferences of singly housed zebrafish (Danio rerio)

Despite the increasing popularity of zebrafish (Danio rerio) as an animal model, the environmental enrichment preferences of this species have been largely unexplored. We sought to determine the preferences of mature female zebrafish that were singly housed with or without...

Environmental enrichment rescues visually-mediated behavior in Ten-m3 knockout mice during an early critical period

Environmental enrichment (EE) has been shown to promote neural plasticity. Its capacity to induce functional repair in models which exhibit profound sensory deficits due to aberrant axonal guidance has not been well-characterized. Ten-m3 knockout (KO) mice exhibit a highly-stereotyped miswiring...

Evaluation of cotton dental rolls as environmental enrichment for mice

Historically, we provided 2 compressed cotton squares for nesting and enrichment. The logistics of managing nesting material distribution, disposal, and costs are major considerations for our program, which provides husbandry to approximately 60,000 rodent cages weekly. We identified cotton dental...
