Zebrafish have more in common with humans than meets the eye. This is why they have become a “go-to” model in neuroscience research. But one difference remains: we walk and they swim.
We are all very familiar with zebrafish as a model species in neuroscience research. Today, let's talk about another fish, the Japanese medaka.
At the Max Planck Institute for Medical Research in Heidelberg, Germany, Groneberg and colleagues researched one of the neural bases for behavior in Danio rerio.
Stress is a natural thing, and how we cope with it differs from person to person. In research, we use the term coping style, something that emerges early on in life for zebrafish.
The zebrafish (Danio rerio) is increasingly being used as model in behavioural, neurobiological and genetic research.
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.
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.
