Coleman, K., Shapiro, S. J. (Eds.). 2021. Behavioral Biology of Laboratory Animals (1st ed). CRC Press, Boca Raton, FL.

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of...

Kasanen, I. H. E., Inhilä, K. J., Nevalainen, J. I. et al. 2009. A novel dietary restriction method for group-housed rats: Weight gain and clinical chemistry characterization. Laboratory Animals 43, 138-148.

Laboratory rodents are usually fed ad libitum. Moderate dietary restriction decreases mortality and morbidity compared with ad libitum feeding. There are, however, problems in achieving dietary restriction. Traditional methods of restricted feeding may interfere with...

Rojas-Carvajal, M., Sequeira-Cordero, A., Brenes, J. C. 2020. Neurobehavioral effects of restricted and unpredictable environmental enrichment in rats. Frontiers in Pharmacology 11, 674.

To study how motivational factors modulate experience-dependent neurobehavioral plasticity, we modify a protocol of environmental enrichment (EE) in rats. We assumed that the benefits derived from EE might vary according to the level of incentive...

Hawkins, P. 2014. Refining housing, husbandry and care for animals used in studies involving biotelemetry. Animals 4(2), 361-373.

Biotelemetry can contribute towards reducing animal numbers and suffering in disciplines including physiology, pharmacology and behavioural research. However, the technique can also cause harm to animals, making biotelemetry a ‘refinement that needs refining’. Current welfare...

Mogil, J. S., Pang, D. S. J., Silva Dutra, G. G. et al. 2020. The development and use of facial grimace scales for pain measurement in animals. Neuroscience & Biobehavioral Reviews 116, 480-496.

The measurement of pain in animals is surprisingly complex, and remains a critical issue in veterinary care and biomedical research. Based on the known utility of pain measurement via facial expression in verbal and especially...

Scarborough, J., Mueller, F., Arban, R. et al. 2020. Preclinical validation of the micropipette-guided drug administration (MDA) method in the maternal immune activation model of neurodevelopmental disorders. Brain, Behavior, and Immunity 88, 461

Pharmacological treatments in laboratory rodents remain a cornerstone of preclinical psychopharmacological research and drug development. There are numerous ways in which acute or chronic pharmacological treatments can be implemented, with each method having certain advantages...

Fischer, M. L., Rodrigues, G. S., Aguero, W. P. et al. 2021. Refinement as ethics principle in animal research: Is it necessary to standardize the environmental enrichment in laboratory animals? Anais da Academia Brasileira de Ciências,

The Environmental enrichment technique, although scientifically recognized for raising the level of animal welfare, has led to the questioning of its influence on the results of experimental research. Thus, the goal is to promote reflection...

Krakenberg, V., Wewer, M., Palme, R. et al. 2021. Regular touchscreen training affects faecal corticosterone metabolites and anxiety-like behaviour in mice. Behavioural Brain Research 401, 113080.

Automated touchscreen techniques find increasing application for the assessment of cognitive function in rodents. However, hardly anything is known about the potential impact of touchscreen-based training and testing procedures on the animals under investigation. Addressing...

Adcock, A., Choleris, E., Denommé, M. et al. 2021. Where are you from? Female mice raised in enriched or conventional cages differ socially, and can be discriminated by other mice. Behavioural Brain Research 400, 113025.

Laboratory rodents raised in environmentally-enriched (EE) cages differ behaviourally and cognitively from conventionally-housed (CH) animals. We hypothesised that mice can detect such differences, testing this using differentially-raised female C57BL/6 s as subjects, and differentially-raised female...

Li, J.-Y., Kuo, T. B. J., Hung, C.-T. et al. 2021. Voluntary exercise enhances hippocampal theta rhythm and cognition in the rat. Behavioural Brain Research 399, 112916.

Regular exercise promotes learning and memory functions. Theta activity is known to relate to various cognitive functions. An increase in theta power may be related to higher cognitive functioning and learning functions. However, evidence is...
