Environmental Enrichment

Includes structural, behavioral, food, and auditory enrichment.

Mkwanazi, M. V., Kanengoni, A. T., Chimonyo, M. 2018. Pen enrichment and sex interaction on growth performance and metabolite concentrations of autochthonous Windsnyer pigs kept in a high stocking density. Canadian Journal of Animal

The objective of the study was to determine the interaction of pen enrichment and sex on growth performance and blood metabolite concentrations of Windsnyer pigs. Forty-eight growing Windsnyer pigs of both sexes, with an average...

Wang, H., Li, Q, Tang, H. et al. 2019. The activated newborn neurons participate in enriched environment induced improvement of locomotor function in APP/PS1 mice. Brain and Behavior 9(7), e01316.

Alzheimer's disease (AD) is an age‐related neurodegenerative disorder. One of the pathological features of AD is neuronal loss in brain regions associated with cognition, particularly the hippocampus. An enriched environment (EE) can facilitate neuronal plasticity...

Bliss-Moreau, E., Baxter, M. G. 2019. Interest in non-social novel stimuli as a function of age in rhesus monkeys. Royal Society Open Science 6(9), 182237.

Human cognitive and affective life changes with healthy ageing; cognitive capacity declines while emotional life becomes more positive and social relationships are prioritized. This may reflect an awareness of limited lifetime unique to humans, leading...

Fernandez, E. J., Timberlake, W. 2019. Foraging devices as enrichment in captive walruses (Odobenus rosmarus). Behavioural Processes 168, 103943.

Stereotypies in captive animals are typically defined as repetitive, invariant behavioral patterns with no obvious goal or function. They are often attributed to boredom or fear and treated by introducing occupational stimuli. The present work...

Moser, J., Burla, J.-B., Gygax, L. 2019. Executing specific foraging behaviours does not represent a general goal state of foraging in dry sows (Sus scrofa). Behavioural Processes 164, 115-122.

Intensively housed domestic pigs (Sus scrofa) have little opportunity to perform diverse foraging behaviour though they still seem strongly motivated to do so. Here, we investigated whether the execution of specific behaviours may in itself...

Modlinska, K., Chrzanowska, A., Pisula, W. 2019. The impact of changeability of enriched environment on exploration in rats. Behavioural Processes 164, 78-85.

Although the positive effect of environmental enrichment on animals’ cognitive capacities is well-known, it remains unclear what role changeability plays in this context. Our study aims to analyse the impact of environmental changeability on the...

Mora-Gallegos, A., Fornaguera, J. 2019. The effects of environmental enrichment and social isolation and their reversion on anxiety and fear conditioning. Behavioural Processes 158, 59-69.

Animal models of fear and anxiety provide important insight into anxiety-related symptoms in humans. Environmental physical conditions and social contact influence behavior and brain plasticity particularly at early developmental stages and have long lasting effects...

Perdue, B. M., Beran, M. J., Washburn, D. A. 2018. A computerized testing system for primates: Cognition, welfare, and the Rumbaughx. Behavioural Processes 156, 37-50.

Innovations in apparatus technology come about for a variety of reasons such as the need to use the same methodology with various species, the opportunity to present dynamic and carefully controlled stimuli, the goal of...

Papadakakis, A., Sidiropoulou, K., Panagis, G. 2019. Music exposure attenuates anxiety- and depression-like behaviors and increases hippocampal spine density in male rats. Behavioural Brain Research 372, 112023.

Epidemiological and clinical studies suggest that early-life stress (ELS) may lead to the development of mental disorders in adulthood. Maternal separation (MS) is a valid animal model of ELS that produces detrimental effects on brain...

Estrada, C., Cuenca, L., Cano-Fernandez, L. et al. 2019. Voluntary exercise reduces plasma cortisol levels and improves transitory memory impairment in young and aged Octodon degus. Behavioural Brain Research 373, 112066.

Sleep deprivation (SD) has been reported to induce transient cognitive impairment in functional domains commonly affected in dementia, including memory. Indeed, sleep disturbance has been proposed as an early marker for Alzheimer’s disease (AD). SD...
