Barker, T. H., Bobrovskaya, L., Howarth, G. S. et al. 2017. Female rats display fewer optimistic responses in a judgment bias test in the absence of a physiological stress response. Physiology & Behavior 173, 124-131.

Metabolic cages are a type of housing used in biomedical research. Metabolic cage housing has been demonstrated to elicit behavioural and physiological changes in rodents housed within them. The nature of this effect has been...

Polissidis, A., Zelelak, S., Nikita, M. et al. 2017. Assessing the exploratory and anxiety-related behaviors of mice. Do different caging systems affect the outcome of behavioral tests? Physiology & Behavior 177, 68-73.

Ample studies have shown that housing can affect the health, welfare and behavior of mice and therefore, the outcomes of certain experiments. The aim of this study was to investigate if three widely used housing...

Makowska, I. J., Weary, D. M. 2016. Differences in anticipatory behaviour between rats (Rattus norvegicus) housed in standard versus semi-naturalistic laboratory environments. PLOS ONE 11(1), e0147595.

Laboratory rats are usually kept in relatively small cages, but research has shown that they prefer larger and more complex environments. The physiological, neurological and health effects of standard laboratory housing are well established, but...

Hirsjarvi, P., Valiaho, T. 1995. Gentled and nonhandled Wistar rats in a mildly novel open-field situation. Scandinavian Journal of Laboratory Animal Science 22(3), 265-269.

Open-field behaviour of individually gentled and nonhandled adult male Wistar rats was studied in a mildly novel test situation. The gentled rats were more active and showed fewer signs of fear on the first trial...

Roberts, S., Van Loo P., Schultz, P. et al. 2006. Stress and distress: A discussion by the Refinement and Enrichment Forum. Animal Technology and Welfare 5(2), 99-102.

The question was asked: "The terms 'stress' and 'distress' are often used in the scientific literature but usually without a definition. If you use these terms, how do you define them? What are the signs...

Li, W. J., Yu, H., Yang, J. M. et al. 2010. Anxiolytic effect of music exposure on BDNFMet/Met transgenic mice. Brain Research 1347, 71-79.

Brain-derived neurotrophic factor (BDNF) has been reported to play important roles in the modulation of anxiety, mood stabilizers, and pathophysiology of affective disorders. Recently, a single nucleotide polymorphism (SNP) in the BDNF gene (Val66Met) has...

Õkva, K., Nevalainen, T., Mauranen, K. et al. 2010. The effect of three different items of cage furniture on the behaviour of male C57BL/6J mice in the plus-maze test. Animal Welfare 19(4), 401-409.

The aim of this study was to assess the effects of specific regimens of enrichment on the behaviour of C57BL/6J mice in the elevated plus-maze test (EPM). A total of 192 male C57BL/6J mice were...

Brydges, N. M., Leach, M., Nicol, K. et al. 2011. Environmental enrichment induces optimistic cognitive bias in rats . Animal

People's affective or emotional state can alter their cognitive processing, biasing interpretation of ambiguous stimuli. Those in a more positive state interpret such stimuli in a more optimistic manner than those in a negative state...
