How to measure complex exploratory behavior in larval zebrafish

Behavioral tests as the open field may overlook complex patterns of behavior. Today our guest bloggers explain about a new set-up for zebrafish larvae.

4 Facts about zebrafish and zebrafish larvae

Did you know that zebrafish larvae are able to detect minute movement in the water and that zebrafish are better than fruit flies? Read all 4 facts!

Zebrafish provide key insights into alcohol addiction

Why is it that when people drink, only small subsets of individuals develop an alcohol addiction? Steven Tran from the Gerlai Lab tells us why zebrafish are very helpful in the search for the answer to this question.

Seizing fish: a high-throughput screen for novel antiepileptic drugs

The lab of Prof. Richard Baines investigates how the electrical development of neurons is regulated. His research was long based on the larvae of fruitfly, but the lab recently started using zebrafish larvae.

How to capture the 3D swimming patterns of fish

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.

How to measure a zebrafish larva’s highly stereotyped response to water motion?

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.

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 in zebrafish (Danio rerio)

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

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

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

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 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.
