Vaughan, L. M., Dawson, J. S., Porter, P. R. et al. 2014. Castration promotes welfare in group-housed male Swiss outbred mice maintained in educational institutions. JAALAS 53(1), 38-43.

Educational institutions maintain group-housed mice of both sexes for training veterinarians and technicians in husbandry, medication, and sampling procedures. Mice kept in all-male groups may experience poor welfare due to fighting. Castrated mice may be...

Monteiro, B. M., Moreira, F. A., Massensini, A. R. et al. 2014. Enriched environment increases neurogenesis and improves social memory persistence in socially isolated adult mice. Hippocampus 24(2), 239-248.

Social memory consists of the information necessary to identify and recognize cospecifics and is essential to many forms of social interaction. Social memory persistence is strongly modulated by the animal's experiences. We have shown in...

Kulesskaya, N., Karpova, N. N., Ma, L. et al. 2014. Mixed housing with DBA/2 mice induces stress in C57BL/6 mice: Implications for interventions based on social enrichment. Frontiers in Behavioral Neuroscience 8, 257.

Several behavioral interventions, based on social enrichment and observational learning are applied in treatment of neuropsychiatric disorders. However, the mechanism of such modulatory effect and the safety of applied methods on individuals involved in social...

Gregoire, C., Bonenfant, D., Le Nguyen, A. et al. 2014. Untangling the influences of voluntary running, environmental complexity, social housing and stress on adult hippocampal neurogenesis. PLOS ONE 9(1), e86237.

Environmental enrichment (EE) exerts powerful effects on brain physiology, and is widely used as an experimental and therapeutic tool. Typical EE paradigms are multifactorial, incorporating elements of physical exercise, environmental complexity, social interactions and stress...

Greenberg, G. D., Howerton, C. L., Trainor, B. C. 2014. Fighting in the home cage: Agonistic encounters and effects on neurobiological markers within the social decision-making network of house mice (Mus musculus). Neuroscience Letters 566, 151-155.

Inbred strains of mice, such as C57Bl/6, have become preferred animal models for neurobehavioral studies. A main goal in creating inbred lines is to reduce the effects of individual genetic variation on observed phenotypes. Most...

Febinger, H.Y., George, A., Priestley, J. et al. 2014. Effects of housing condition and cage change on characteristics of sleep in mice. JAALAS 53(1), 29-37.

Although human subjects are widely used to study sleep and sleep disorders, animals have been invaluable in developing our understanding of the physiology of sleep and underlying mechanisms of sleep disorders. Environmental stimuli are likely...

Doulames, V., Lee, S., Shea, T. B. 2014. Environmental enrichment and social interaction improve cognitive function and decrease reactive oxidative species in normal adult mice. International Journal of Neuroscience 124(5), 369-376.

Environmental stimulation and increased social interactions stimulate cognitive performance, while decrease in these parameters can exacerbate cognitive decline as a function of illness, injury, or age. We examined the impact of environmental stimulation and social...

Burman, O., Buccarello, L., Redaelli, V. et al. 2014. The effect of two different individually ventilated cage systems on anxiety-related behaviour and welfare in two strains of laboratory mouse. Physiology & Behavior 124, 92-99.

The environment in which a laboratory animal is housed can significantly influence its behaviour and welfare, acting as a potential confounding factor for those studies in which it is utilised. This study investigated the impact...

Burlingame, L. A., Lofgren, J. L. 2014. Presence of nesting material does not prevent ability to accurately identify sick or de

Whether nesting material assists or hinders the ability to identify sick mice during routine health check is a widely debated topic. Currently, our large and diverse academic research institution is exploring the possibility of providing...
