The bat - moth aerial battle in 3D

Posted by Fabrizio Grieco on May 5, 2016

Any insect that flies at night must deal with bat predation. Take a moth, for example. Moths arrived first on the evolutionary stage; when much later on bats appeared with their sophisticated apparatus for echolocating prey, moths were forced to change or die. Some species developed ears to hear the approach of a bat; this generally evokes evasive flight maneuvers like loops and dives. Other species acquired distasteful chemicals that gave them a repugnant or poisonous taste. Some even developed the ability to produce sounds that seem to confuse, and sometimes thwart, an attacking bat.

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.

Tracking zebrafish in 3D

Tracking zebrafish in 3D at the Zebrafish Behavioral Neuroscience and Neurophenotyping workshop

By Christine Buske

Zebrafish are an exciting, but still relatively new, model organism growing in popularity in behavioral neuroscience. We have highlighted recent behavioral work using zebrafish extensively, but compared to other models there are few textbooks or protocols available to those entering the field. Compared to mouse and rat phenotyping, the zebrafish community has a long way to go. Not only when it comes to protocol development and the availability of handbooks, but also with regards to professional training.

Insect 3d tracking system at Bioforsk

Posted by G. Smit on Jun 15, 2011

In northern Norway, pest species such as the blowfly (Calliphora vicina) cause great economic losses in the fish industry. These insects lay their eggs in high quality stockfish which is hung out to dry in the open air. Researchers at Bioforsk (a governmental institution that, among other things, operates a biological pest control facility) aim to find methods to prevent this devastation, starting with the study of the behavior of blowflies. By understanding how they locate their target and which visual and olfactory stimuli they use, a first step is made towards creating methods to prevent damages to the stockfish industry.
