Fresh façades for rodent homes: Revisiting enrichment naturally

Currently, enrichment consists of a variety of plastic toys to promote natural behaviors, but why use artificial devices when you could use natural materials like the animals experience in their native environment? ... From these three tests it appears that...

The effects of music on animal physiology, behavior and welfare

Physiological and psychological effects of listening to music have been documented in humans. The changes in physiology, cognition and brain chemistry and morphology induced by music have been studied in animal models, providing evidence that music may affect animals similarly...

Noisy construction does not have to generate noisy data

Our institution opened the Jan and Dan Duncan Neurologic Research Institute (NRI) in November of 2010. This facility houses a team of world renowned researchers working with mice and rats to develop treatments for childhood neurologic disorders. The second and...

Pro-social behavior in rats is modulated by social experience

In mammals, helping is preferentially provided to members of one's own group. Yet, it remains unclear how social experience shapes pro-social motivation. We found that rats helped trapped strangers by releasing them from a restrainer, just as they did cagemates....

Tickling during adolescence alters fear-related and cognitive behaviors in rats after prolonged isolation

Social interactions during adolescence are important especially for neuronal development and behavior. We recently showed that positive emotions induced by repeated tickling could modulate fear-related behaviors and sympatho-adrenal stress responses. In the present study, we examined whether tickling during early...

The impact of social isolation on immunological parameters in rats

In various toxicological studies, single housing of rodents is preferred to standardize for regulatory purposes. However, housing conditions can have severe, often underestimated, impact on results in toxicological examinations. As different husbandry conditions have been shown to impose stress, we...

Effects of a complex housing environment on heart rate and blood pressure of rats at rest and after stressful challenges

Housing enrichment for rodents continues to be a discussion topic within the animal care community. The objective of this study was to determine the extent to which a complex housing environment affects heart rate, blood pressure, and activity of rats...

Effects of single compared with pair housing on hypothalamic-pituitary-adrenal axis activation and low-dose heroin place conditioning in adult male Sprague-Dawley rats

Whether social isolation of adult rats under standard laboratory conditions produces significant long-term alterations in behavior and physiology is unclear. In the present study, male Sprague–Dawley rats were singly or paired-housed for 10 wk. During this period, they were tested...

Enrichment with wood blocks does not affect toxicity assessment in an exploratory toxicology model using Sprague-Dawley rats

Environmental enrichment in rodents may improve animal well-being but can affect neurologic development, immune system function, and aging. We tested the hypothesis that wood block enrichment affects the interpretation of traditional and transcriptomic endpoints in an exploratory toxicology testing model...
