Jirkof, P., Abdelrahman, A., Bleich, A. et al. 2020. A safe bet? Inter-laboratory variability in behaviour-based severity assessment. Laboratory Animals 54(1), 73–82.

Evidence-based severity assessment is essential as a basis for ethical evaluation in animal experimentation to ensure animal welfare, legal compliance and scientific quality. To fulfil these tasks scientists, animal care and veterinary personnel need assessment...

Weegh, N., Füner, J., Janke, O. et al. 2020. Wheel running behaviour in group-housed female mice indicates disturbed wellbeing due to DSS colitis. Laboratory Animals 54(1), 63–72.

Voluntary wheel running (VWR) behaviour is a sensitive indicator of disturbed wellbeing and used for the assessment of individual experimental severity levels in laboratory mice. However, monitoring individual VWR performance usually requires single housing, which...

Mallien, A. S., Häger, C., Palme, R. et al. 2020. Systematic analysis of severity in a widely used cognitive depression model for mice. Laboratory Animals 54(1), 40–49.

Animal models in psychiatric research are indispensable for insights into mechanisms of behaviour and mental disorders. Distress is an important aetiological factor in psychiatric diseases, especially depression, and is often used to mimic the human...

Smith, B. J., Bruner, K., Kendall, L. V. 2019. Female- and intruder-induced ultrasonic vocalizations in C57BL/6J mice as proxy indicators for animal wellbeing. Comparative Medicine 69(5), 374–383.

Female urine-induced male mice ultrasonic vocalizations (FiUSV) are ultrasonic vocalizations produced by adult male mice after presentation of adult female urine, whereas intruder-induced ultrasonic vocalizations (IiUSV) are produced by resident adult female mice when interacting...

Dauchy, R. T., Blask, D. E., Hoffman, A. E. et al. 2019. Influence of daytime LED light exposure on circadian regulatory dynamics of metabolism and physiology in mice. Comparative Medicine 69(5), 350–373.

Light is a potent biologic force that profoundly influences circadian, neuroendocrine, and neurobehavioral regulation in animals. Previously we examined the effects of light-phase exposure of rats to white light-emitting diodes (LED), which emit more light...

Mei, J., Kohler, J., Winter, Y. et al. 2020. Automated radial 8-arm maze: A voluntary and stress-free behavior test to assess spatial learning and memory in mice. Behavioural Brain Research 381, 112352.

The radial arm maze (RAM) is a common behavioral test to assess spatial working and reference memory in mice. However, conventional RAM experiments require a substantial degree of manual handling and animals are usually subjected...

McAllister, B. B., Thackray, S. E., Garciá de la Orta, B. K. et al. 2020. Effects of enriched housing on the neuronal morphology of mice that lack zinc transporter 3 (ZnT3) and vesicular zinc. Behavioural Brain Research 379, 112336.

In the central nervous system, certain neurons store zinc within the synaptic vesicles of their axon terminals. This vesicular zinc can then be released in an activity-dependent fashion as an intercellular signal. The functions of...

Peterman, J.L., White, J.D., Calcagno, A. et al. 2020. Prolonged isolation stress accelerates the onset of Alzheimer’s disease-related pathology in 5xFAD mice despite running wheels and environmental enrichment. Behavioural Brain Researc

Research has demonstrated that stress can exacerbate AD pathology in transgenic mouse models of AD. The purpose of the present studies was to extend this work by determining whether a social stressor, isolation stress, would...

Mertens, S., Gass, P., Palme, R. et al. 2020. Effect of a partial cage dividing enrichment on aggression-associated parameters in group-housed male C57BL/6NCrl mice. Applied Animal Behaviour Science 224, 104939.

Group-housing is highly important for social animals. Group-housing of male mice in captivity though often leads to aggression with partially disastrous consequences for the animals as well as for the quality of experimental data. In...

Zidar, J., Weber, E. M., Ewaldsson, B. et al. 2019. Group and single housing of male mice: Collected experiences from research facilities in Sweden. Animals 9(12), 1010.

The mouse is the most commonly used mammal in scientific research, and housed in research facilities around the world. Mice are a social species, but when housing male mice together in a confined environment in...
