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.
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.
PCBs are synthetic molecules that were used in transformers, electric motors, and more applications. It was quickly discovered that these molecules are toxic, and subsequently, they were banned.
By this point, we do not need to tell you how popular zebrafish are. We also probably do not need to point out the great technological advances that are being made in research because of the use of optogenetics.
Ever heard of quantum dots? These dots are nanoparticles made of a semiconductor material, which have unique optical properties, making them of great interest for fields such as biological imaging, medical diagnostics.
Often in animal research, animals with a certain genetic alteration are compared to a “wild-type”. One might assume that there is no differences between wild-types, but many different strains of wild-type animals are used.
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.
Zebrafish are not the first species one might think of as being exposed to alcohol in their natural environment.
Recognizing the lack of hands-on education, Dr. Kalueff has started organizing zebrafish behavioral neuroscience and phenotyping workshops. The workshops ran just before and after the SfN annual meeting, October 2012.
I have been reading a lot about zebrafish research lately and I thought it would be nice to share some of my favorite articles with you.
