Rybalko, N., Suchánková, Š., Bureš, Z. et al. 2023. Mice prone to tinnitus after acoustic trauma show increased pre-exposure sensitivity to background noise. Frontiers in Behavioral Neuroscience 17.
Noise-induced tinnitus is generally associated with hearing impairment caused by traumatic acoustic overexposure. Previous studies in laboratory animals and human subjects, however, have observed differences in tinnitus susceptibility, even among individuals with similar hearing loss...
Parsons, M. H., 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.
Rodents, laboratory rats and mice, have been used as models in experimental research for almost two centuries (Keeler, 1947; Bolles and Woods, 1964; Nishioka, 1995; Guénet and Bonhomme, 2003). During this time, it has been...
Nunes, S. 2023. Animal-friendly behavioral testing in field studies: Examples from ground squirrels. Frontiers in Behavioral Neuroscience 17.
Field studies of behavior provide insight into the expression of behavior in its natural ecological context and can serve as an important complement to behavioral studies conducted in the lab under controlled conditions. In addition...
McKay, L., Hunninck, L., Sheriff, M. 2020. A field-based adaptation of the classic morris water maze to assess learning and memory in a free-living animal. Animal Behavior and Cognition 9(4), 396–407.
Free-living animals rely on cognitive functions, such as learning and memory, for numerous aspects of their survival. However, research involving these mechanisms is often limited to the laboratory where animals are far removed from natural...
Lang, B., Kahnau, P., Hohlbaum, K. et al. 2023. Challenges and advanced concepts for the assessment of learning and memory function in mice. Frontiers in Behavioral Neuroscience 17.
The mechanisms underlying the formation and retrieval of memories are still an active area of research and discussion. Manifold models have been proposed and refined over the years, with most assuming a dichotomy between memory...
Gazes, R. P., Brown, E. K., Basile, B. M. et al. 2013. Automated cognitive testing of monkeys in social groups yields results comparable to individual laboratory-based testing. Animal Cognition 16(3), 445–458.
Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under...
Bramati, G., Stauffer, P., Nigri, M. et al. 2023. Environmental enrichment improves hippocampus-dependent spatial learning in female C57BL/6 mice in novel IntelliCage sweet reward-based behavioral tests. Frontiers in Behavioral Neuroscience 17.
The IntelliCage is an automated home-cage system that allows researchers to investigate the spontaneous behavior and learning abilities of group-housed mice. The IntelliCage enables us to increase the standardization and reproducibility of behavioral outcomes by...
Becker, L., Mallien, A. S., Pfeiffer, N. et al. 2023. Evidence-based severity assessment of the forced swim test in the rat. PLOS ONE 18(10), e0292816.
The forced swim test (FST) is a traditional assay, which has been used for more than 40 years to assess antidepressant effects of novel drug candidates. In recent years, a debate about the test has...
Alef, R., Blaser, R. E. 2023. Social group during housing and testing modulates the effect of ethanol on zebrafish (Danio rerio) behavior. Behavioural Processes 209, 104877.
Zebrafish (Danio rerio) are a popular model organism in behavioral pharmacology research due to many genetic and neurological similarities with humans. As a social species, the presence (or absence) of conspecifics during housing and testing...
