Domestication has a considerable effect on the behavior of animals. The dramatic change in their environment and provision of food alter the need for behaviors such as exploration. But what exactly is the difference?
Some might argue that laboratory mice are not the same as wild mice, yet they remain capable of performing the innate, routine behaviors necessary to survive in natural environments, such as courtship and nest-building,
A commonly used assay for assessment of fear in animals is the novel environment test.In this test, an animal is placed in an arena for a particular time period and behaviors are scored.
Here are six recommendations the authors list to improve the translational and predictive value of behavioral readouts.
Scientists have been performing open field tests for quite some time now. Over the years it has become one of the most popular tests in rodent behavioral research. So what’s not to love?
We all know of animals that are able to regenerate: lizards that grow back their tails, flatworms that can grow into new worms when cut in half. Zebrafish have this special ability as well.
Zebrafish. This little fish is a vertebrate, and a relatively complex one. Looking at the major neurotransmitters and hormones that are investigated in neuroscience, they are as good of a model as many mammalian species.
Some disorders cannot simply be diagnosed with a blood test or tissue-culture. Autism Spectrum Disorder (ASD) is a good example; its diagnosis relies upon behavioral tests and questionnaires.
Why do wolves howl? From research, movies, and even television series, we learn that wolves cry out to each other to facilitate the reassembling of a pack when members have strayed.
How to mark zebrafish without compromising their behavior? They may have just found the answer to this at the University of Toronto. Cheung et al. tried out a method using subcutaneous injection with dyes.
