CatWalk XT gait analysis versus treadmills

Traditionally, there are two fundamentally different ways to analyze gait in animals. One can either observe or measure gait in an unrestricted manner, or in a forced manner, as seen when using a treadmill or treadwheel.

Testing without stress: high-throughput phenotyping

The ability to recognize harmful situations and respond accurately is important for the survival of any animal. In order to respond to these situations the animal must be able to learn, remember, and alter its behavior.

Tracking zebrafish activity to study a key element in circadian rhythmicity

Zebrafish are a popular model of choice for many researchers, including chronobiologists. That’s because zebrafish rapidly develop their ‘inner clock’ (circadian system) – and because this system is highly light-entrainable.

Observing monkey behavior – cracking the nut

We already know some monkeys display above average intelligence. One way by which we can tell is their use of tools. Studies have shown that capuchin monkeys use boulders and logs as anvils upon which they can crush nuts.

Zebrafish with Parkinson's

Parkinson’s Disease (PD) is one of the main neurodegenerative diseases and many researchers are involved in investigating this disease and developing treatments

Connects some dots - cognitive impairment and cranial radiation

On a yearly basis, an estimated 20.000 individuals are diagnosed with primary brain tumors in the United States alone. About ten times that number of patients will receive treatment for primary or metastatic brain cancer.

Beautiful birds and UV – What we cannot see

Don’t we all enjoy the variety and intensity of bird colors? Male birds have perhaps the most impressive color display in nature.

How to get reliable results on object recognition using video tracking

In the beginning of this year I wrote a post about the Morris water maze test, a popular and well-validated paradigm to study learning and memory in rats and mice.

Zebrafish tracking to uncover subtle effects of embryonic alcohol exposure

Zebrafish are not the first species one might think of as being exposed to alcohol in their natural environment.

Why it is smart to test your animal in its home cage

Behavior of laboratory rodents is often studied in well-controlled, simple experiments, in an environment that is fundamentally different from the animal’s home cage.
