how-young-zebrafish-cope-with-stress

How young zebrafish cope with stress

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.
inhibitory-avoidance-learning-zebrafish

Inhibitory avoidance learning in zebrafish (Danio rerio)

The zebrafish (Danio rerio) is increasingly being used as model in behavioural, neurobiological and genetic research.
zebrafish-regenerate-measure-their-recovery

How zebrafish regenerate (and how to measure their recovery)

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.
how-zebrafish-are-changing-neuroscience

How zebrafish are changing neuroscience

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

How to mark zebrafish without compromising their behavior

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.
testing-pcbs-toxicity-behavior-zebrafish

Testing PCBs toxicity - behavior in zebrafish and their offspring

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.
zebrafish-and-optogenetics

How zebrafish and optogenetics are great for investigating stress

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.
quantum-dots-toxicity-zebrafish-larvae

The effects of quantum dots on zebrafish larvae locomotor behavior

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.
tracking-wide-variety-animals

Tracking a wide variety of animals

Video tracking is used to track a widevariety of animal species in even more different test arenas. From insects of 1 mm on leaf discs, to monkeys in a cage, or zebra fish in an aquarium.
zebrafish-behavioral-differences

Zebrafish research: behavioral differences between wild-type strains

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.
