How zebrafish are changing neuroscience

Posted by G. Smit on May 1, 2014

Zebrafish. This small little fish is a vertebrate, and a relatively complex one at that. Looking at all the major neurotransmitters and hormones that are investigated in neuroscience, they are as good of a model as many mammalian species. Indeed, recent studies have shown how they are ideal  for testing in behavioral domains such as anxiety, sociality, sleep, reward, and cognition.

10 Reasons to visit Neuroscience 2013

Posted by Annelies Verkerk on Nov 7, 2013

Do you attend conferences? Imagine networking with 30,000 fellow neuroscientists in beautiful San Diego, California. Now add the sun-soaked beaches (yes, even in November), a 0% chance of rain, many social events, and 15,000 scientific presentations: that’s why you should attend Neuroscience 2013! Not convinced yet? Here are 10 reasons why you should attend Neuroscience 2013!

Zebrafish research: behavioral differences between wild-type strains

Posted by G. Smit on Aug 20, 2013

Often in animal research, animals with a certain genetic alteration are compared to a “wild-type” (this being the ‘normal’ rat, mouse, or zebrafish). One might assume that there is no difference between one wild-type animal and the next, but in fact, many different strains of wild-type animals are used.

Many wild-type zebrafish strains
The same is true for zebrafish. Many studies talk of wild-type animals, but the strain is not always mentioned. Furthermore, wild-type fish can be acquired at the pet shop, from a commercial scientific supplier, or simply caught in the wild. Vignet et al. noticed that there have been reports of differences in behavior between wild-type strains, and therefore they stress the importance of matching the most appropriate strain to the behavioral test.
