What you need to know about the CatWalk gait analysis method
Discover the history and technology of CatWalk XT! CatWalk XT is an automated gait analysis system for rodents, initially created for research on rat models for spinal cord injury. The system has since expanded to other species, such as mice and marmosets.
Learn how the CatWalk XT system has evolved since its inception in 2001 by Dr. Frank Hamers to its present state, featuring green LED Illuminated Footprints technology and a high-speed digital camera. Understand how the accompanying software analyzes over 50 spatial and temporal parameters, providing crucial insights for researchers studying various disease models.
Essential features of the CatWalk XT such as the goal box encourage straight, even runs, which together with the adjustable side walls can accommodate different animal sizes. But the software also provides powerful data visualization capabilities, which allows for an intuitive understanding and presentation of research findings.
With over 2,400 publications featuring CatWalk XT, the system has become a popular choice among researchers seeking an efficient and effective solution for gait analysis in rodents.

Does well plate size matter? A methodological study in zebrafish
Does the size of the well plate you in zebrafish research impact your results? This insightful blog post explores the use of the DanioVision observation chamber to study zebrafish embryos and larvae and highlights a study by Wolter and Svoboda that investigates how circadian rhythms, based on locomotion, change depending on the well plate size used in your study.
The authors raise concerns about the potential bias introduced by using different well plate sizes, as zebrafish larvae exhibit higher amounts of locomotion in larger areas.The study's findings suggest that long-term experiments in 48 and 96 well plates may impose stress on zebrafish larvae due to space constraints, which could impact nervous system function and/or behavior.
Moreover, the researchers concluded that the typical high-throughput method in 96 well plates may increase individual variability of circadian rhythms. Based on these results, the authors recommend using 24 well plates for long-term zebrafish behavioral experiments to increase standardization, despite shifting from a high-throughput to medium-throughput set-up.

Measuring behavior of coral larvae in response to antifouling coatings
Measuring coral larvae behavior? Yes! One of the many other-than-standard animal models possible with the flexibility EthoVision XT offers. This blog post describes the studies done by Lisa Röpke from the Leibniz Centre for Tropical Marine Research.
She highlights the importance of studying coral larvae's behavioral responses to potentially non-toxic alternatives of antifoulings, which are specialized coatings applied to ships' hulls that can contain toxic compounds that negatively impact marine life, including coral reefs.
Röpke's study focuses on the behavior of Acropora millepora coral larvae, using Noldus' EthoVision XT to track and analyze their swimming velocity and activity during exposure to three different antifouling coatings. The results show significant decreases in mobility, emphasizing the importance of measuring behavior in ecotoxicological research.
The study also provides a valuable resource for using EthoVision XT with coral larvae, promoting the standardization of research protocols in similar studies.

Using video tracking to study operant behavior in rodents
Operant behavior is a form of learning and memory linked to reward and punishment. Typically, operant behavior is measured using an operant conditioning chamber (Skinner box), where rodents learn to perform tasks to receive positive or negative consequences.
Video tracking technology, such as EthoVision XT, plays an essential role in observing and analyzing rodent behavior during these tasks, allowing researchers to collect and analyze multiple variables simultaneously.
A recent study in obesity research exemplifies the power of video tracking in operant conditioning tasks. Using Noldus' PhenoTyper and EthoVision XT, the researchers examined diet-induced obese mice, assessing the effects of gut bacteria on the rodents' reward system.
The study showcases how video tracking technology has significantly improved our ability to follow and analyze behavior during training and testing sessions in operant conditioning tests, providing valuable insights into learning and memory in rodents.
