How to capture the 3D swimming patterns of fish

Posted by G. Smit, MSc & A.H. Macbeth, PhD on Oct 1, 2015

We have learned that zebrafish have much more in common with humans than meets the eye, which is why they have become a “go-to” model in neuroscience research. But one obvious difference remains:  we walk and they swim, which means movement in 3 dimensions. So while video tracking from one camera angle (e.g. above) can give us a lot of information about the movement of humans (or rodents), all the information from the third dimension (depth) is entirely missed from single camera tracking.

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!

Smelly feet and heat – how malaria mosquitoes find their hosts

Posted by Olga Krips on Oct 15, 2013

Why is it that if there is a mosquito in my bedroom, usually it won’t bite me, but it does bite my partner? It seems that mosquitoes use human body odor to locate suitable hosts, and different people smell differently to mosquitoes.

However, it is not only body odor, but also body heat, CO2 from breathing and wind direction may also be important for the mosquitoes to find you. Furthermore, different mosquito species use different cues. For many mosquito species it is still not known exactly what they do to find their hosts.
