Quante, S. M., Siewert, V., Palme, R. et al. 2023. The power of a touch: Regular touchscreen training but not its termination affects hormones and behavior in mice. Frontiers in Behavioral Neuroscience 17, 1112780.

Touchscreen-based procedures are increasingly used in experimental animal research. They not only represent a promising approach for translational research, but have also been highlighted as a powerful tool to reduce potential experimenter effects in animal...

Peruga, M., Kawala, B., Sarul, M. et al. 2023. Are currently selected laboratory animals useful in the research of how female hormones influence orthodontic biomechanics? Animals 13(4), 629.

Animal testing was and remains the only method of introducing a certain treatment and medical procedure on humans. On the other hand, animals have their rights resulting from applicable legal acts, including Directive 2010/63/EU and...

Pellis, S. M., Pellis, V. C., Ham, J. R. et al. 2022. The rough-and-tumble play of rats as a natural behavior suitable for studying the social brain. Frontiers in Behavioral Neuroscience 16, 1033999.

Laboratory rats have been an important model species with which to study the neurobiology of rough-and-tumble play (RTP). RTP in rats involves competition to gain access to the partner’s nape of the neck, which is...

Parsons, M., Stryjek, R., Fendt, M. et al. 2023. Making a case for the free exploratory paradigm: Animal welfare-friendly assays that enhance heterozygosity and ecological validity. Frontiers in Behavioral Neuroscience 17, 1228478.

Animal welfare considerations are an essential part of scientific research. If animals may suffer, then even 26 the most promising research plans can be delayed or rejected and the resulting data may be questionable. 27...

Palumbo, G., Kunze, L. H., Oos, R. et al. 2023. Longitudinal studies on Alzheimer disease mouse models with multiple tracer PET/CT: Application of reduction and refinement principles in daily practice to safeguard animal welfare during progressive ag

Longitudinal studies on mouse models related to Alzheimer disease (AD) pathology play an important role in the investigation of therapeutic targets to help pharmaceutical research in the development of new drugs and in the attempt...

Orosz, G. 2022. Mouse food hopper dividers for a refined feeding method. Animal Technology and Welfare 21(3), 160–176.

This project aimed to establish whether a different method of presenting diet “ad-libitum” to laboratory mice could lower the negative consequences of exceess food, such as decreased quality, palatability and increased cost. The main aim...

Nuber, M., Gonzalez-Uarquin, F., Neufurth, M. et al. 2022. Development of a 3D simulator for training the mouse in utero electroporation. PLOS ONE 17(12), e0279004.

In utero electroporation (IUE) requires high-level training in microinjection through the mouse uterine wall into the lateral ventricle of the mouse brain. Training for IUE is currently being performed in live mice as no artificial...

Müller, K., Lengheimer, T., Kral-Pointner, J. B. et al. 2022. Exposure to soiled bedding reduces abnormal repetitive behaviors in mice. Frontiers in Behavioral Neuroscience 16, 1062864.

Hygiene management protocols in laboratory mouse husbandries worldwide most commonly employ soiled bedding-exposed sentinel mice to monitor the occurrence of infections in mouse colonies. Using this approach, sentinel mice repeatedly receive a mixture of used...

Mieske, P., Hobbiesiefken, U., Fischer-Tenhagen, C. et al. 2022. Bored at home?—A systematic review on the effect of environmental enrichment on the welfare of laboratory rats and mice. Frontiers in Veterinary Science 9, 899219.

Boredom is an emotional state that occurs when an individual has nothing to do, is not interested in the surrounding, and feels dreary and in a monotony. While this condition is usually defined for humans...

Marquardt, A. E., VanRyzin, J. W., Fuquen, R. W. et al. 2023. Social play experience in juvenile rats is indispensable for appropriate socio-sexual behavior in adulthood in males but not females. Frontiers in Behavioral Neuroscience 16, 1076765.

Social play is a dynamic and rewarding behavior abundantly expressed by most mammals during the juvenile period. While its exact function is debated, various rodent studies on the effects of juvenile social isolation suggest that...
