Mice with Alzheimer’s disease walk well but remember poorly
A large number of genetically engineered mouse models are available to study different aspects of Alzheimer’s disease.

Circadian rhythmicity and other behavioral studies
Many labs use video tracking software to increase the efficiency of their research. In fact, EthoVision XT video tracking software has just reached an impressive milestone: 2000 sites worldwide.

Combining physiology and behavior to create a stress scale for horses
We all are familiar with stress, and how it can have an impact not only on our behavior, but on our bodies and physiology as well. Many people get stress headaches or start to feel sick if they reach high levels of stress.

Plants with more linalool smell good, but taste bad
Plant volatiles play an important role in the interaction between plants and insects that eat them. Insect damage very often induces plants to produce volatiles.

Pesticides in bee colonies affect the behavior of bees
In the past 20 years, populations of honeybees have declined all over the world. This is partly caused by the increased occurrence of parasites and pathogens.

Determining the effect of social hierarchy on foraging in coyotes
Whether it’s an older sibling taking the last piece of cake from their younger sibling or a dominant coyote shoving a subordinate out of the way so it can eat the food, nature has its hierarchies.

The power of zebrafish in the study on Parkinson’s Disease
Zebrafish have proven to be a good model for Parkinson’s Disease (PD) research. They express several highly conserved genes that are associated with PD.

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.
