Four facts about zebrafish and zebrafish larvae

Posted by Annelies Verkerk on Feb 11, 2016

Did you know that zebrafish larvae are able to detect minute movement in the water?

At the Max Planck Institute in Germany, Groneberg and colleagues (Groneberg et al. 2015) showed that larval zebrafish show approach reactions followed by a form of positive taxis and gradual motion damping in response to water flows. That might sound complicated, but what it basically means is that zebrafish larvae are able to detect minute movement in the water and respond in a stereotypical way.

Neuroscience 2015 – Baby steps

Posted by G. Smit on Oct 19, 2015

Sunday, October 18th - After helping out my colleagues set up the booth on Saturday, Sunday was my first ‘actual’ SfN day. As a first-timer, I tried to prepare for Neuroscience 2015, but quickly found that you really cannot. It is overwhelming – in a good way. It is like a playground for scientists and anyone interested in what goes on in the brain. And even though there are enough people here to fill a city, it feels like a welcoming community.

Spending the energy

There is so much going on, that it’s hard to decide what booth to see, which lecture to go to, or which poster to visit.

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

Posted by Guest blogger on Oct 16, 2015

This week we have a guest blog post from Prof. Richard Baines. His lab 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. He kindly agreed to share his insights on our blog.

10 Innovative behavioral studies on Alzheimer’s and Parkinson’s

Posted by G. Smit on Mar 17, 2015

Tomorrow the 12th International Conference on Alzheimer’s and Parkinson’s diseases (ADPD) in Nice, France starts. Last week I blogged about a study on Ginkgo biloba and Alzheimer's, and I thought this would be a great opportunity to highlight some more studies and get you in the mood for the conference. This blog post features 10 interesting studies that use innovative techniques to study models of AD and PD and important underlying neuronal mechanisms.

Most and least popular posts of 2013 (animal behavior research)

Posted by G. Smit on Dec 31, 2013

It seems inevitable: the end-of-year lists. And yes, here at the Noldus blog, you can find them too. I did not want leave 2013 behind us without mentioning our three most popular blog posts on animal behavior research of this year. While 13 might not be a lucky number for some, we have had a great year in which we saw a lot of growth in zebrafish research and the combination of optogenetics and behavior. Not surprisingly, these two topics showed up in our top 3.

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!

Top 5 most popular video tracking blog posts

Posted by G. Smit on Oct 30, 2013

In this post I am looking back at our most popular posts (based on numbers of views) on video tracking. Zebrafish, optogenetics, and Parkinson’s disease are topics that dominate the list, which honestly is no surprise to me. Let me tell you about these 5 posts that are definitely worth a read if you are interested in video tracking research!

At five is Zebrafish with Parkinson’s

The effects of quantum dots on zebrafish larvae locomotor behavior

Posted by G. Smit on Sep 16, 2013

Ever heard of quantum dots? These dots are nanoparticles made of a semiconductor material, which have unique optical properties: the wavelength (and thus color) of their light emission depends on their size, rather than the material they are made of. This is why they are of great interest for fields such as biological imaging, medical diagnostics, drug delivery, and gene therapy.

The power of zebrafish in the study on Parkinson’s Disease

Posted by G. Smit on May 22, 2013

Zebrafish have proven to be a good model for Parkinson’s Disease (PD) research, as I already wrote about in Zebrafish with Parkinson’s. They express several highly conserved genes that are associated with PD. Lopes de Fonseca et al. recently published about another interesting protein that has been linked to cases of PD in humans that run in families (familial).

Zebrafish homologue to human PD gene
Point mutations in ATP13A2 have been linked to several familial cases of PD, and zebrafish also express this gene. In fact, it has a high degree of homology with the human version. This particular study showed that it also plays a crucial role in embryonic development, and that partial knockdown of this gene affected zebrafish larvae behaviorally.
