Environmental Enrichment for Gummivorous Primates
… of the responding zoos provide gum-based enrichment to marmosets (Callimico, Callithrix, and Cebuella- 83%), but only half provide gum to tamarins (Leontopithecus and Saguinus- 50%) and galagos (Galago and Otolemur- 50%). No zoos report feeding gum to baboons (Papio spp.), vervet monkeys …

Effect of environmental enrichment on voluntary salt intake in horses
The aim of this study was to evaluate whether horses consume a significantly different amount of salt from a salt block when a “toy” in the form of an empty plastic bottle was hung in their boxes compared to when no toy was presented to them. This would shed light on whether or not voluntary salt …

Environmental enrichment and serotonergic alterations on depressive-like states in rats
… underlying the etiology of depression, environmental factors play a key role as well. For example, environmental enrichment results in various neurotransmitter alterations, significantly affecting serotonin. To test the efficacy of novel antidepressant drugs in the preclinical laboratory …

Environmental Enrichment and Nursing Therapy with Comatose Patients : Two Case Studies
… could be improved by nursing therapy with environmental enrichment and meaningful systematic orienting stimuli given by professional nurse clinicians and a patient's significant others. The effects of the orienting stimuli were measured by observable changes in arousal patterns in serial …

A quantitative evaluation of environmental enrichment for stream fish at the Tennessee Aquarium
Environmental enrichment is utilized to elevate welfare of animals under human care; it has been shown to increase well-being, promote natural behaviors, and reduce maladaptive behaviors in fishes. I evaluated seasonal mimicking as environmental enrichment in the Tennessee Aquarium’s Ridges to …

Subacute Hippocampal Atrophy Following Traumatic Brain Injury: Relationship to Environmental Enrichment and Vocational Outcome
… beyond the initial 3 months post-injury) via environmental enrichment, drawing on theoretical models and research findings from the fields of environmental enrichment, brain and cognitive reserve, and neuroplastic models of functional recovery from brain injury. Objectives: (a) to examine the …

The differential effects of short-term physical exercise, environmental enrichment and their combination, and short- and long-term environmental enrichment on behavior and associated molecular changes in the brain of C57BL/6 mice
… levels. Evidence suggests that external environmental conditions can modify the effects of aging. Environmental enrichment (EE), where the immediate environment of experimental animals is modified, has been reported to reverse the adverse effects of brain aging. Past studies on EE have, …

Cellular mechanisms of environmental enrichment: Novel discovery-based strategies for target identification for neuropsychiatric disorders
… of the resilience to depression and addiction, environmental enrichment. Environmental enrichment is a non-drug, non-surgical, non-genetic manipulation that produces protective depression and addiction phenotypes. Enriched rats are reared in a large cage with conspecifics and plastic toys that …

Effect of rearing environment and environmental enrichment on behavior and neural development in young pigs
… indicated that the addition of small amounts of environmental enrichment to barren pens greatly reduced blind excitability ratings. Petting by a person (mingling) for 5 minutes once a week was effective. Two enrichment treatments such as mingling and objects (hanging rubber hoses) were more …

Transcriptomics of environmental enrichment and cocaine reveals roles for retinoic acid signaling and ΔFosB in addiction
Environmental enrichment produces protective addiction and depression phenotypes as a non-drug, non-genetic, and non-surgical manipulation in animals. Rats reared in the enriched condition self-administer less cocaine and display antidepressant-like behavior. To understand the molecular mechanisms …

Effects of Environmental Enrichment on Learning a Discrimination Task by Captive White-spotted Bamboo Sharks (Chiloscyllium plagiosum)
… but no studies have investigated the effects of environmental enrichment on sharks’ learning abilities. The main objective of this study was to test the hypothesis that environmental enrichment would improve learning performance in captivity of white-spotted bamboo sharks (Chiloscyllium …

Effects of environmental enrichment on personality traits in juvenile Arctic charr (Salvelinus alpinus) : interplay with brain morphology, growth performance and implication for welfare
… The aims of this study are to investigate how an environmental enrichment affects the personality traits expression and their correlation (i.e., behavioural syndrome) as well as potential association with brain characteristics and growth for Arctic charr welfare implication. I found that physical …
