Stop, Science time! Scientists are playing to baby in order to understand how they develop their hearing underwater. (Image: [[https://www.freepixels.com/class=|https://www.freepixels.com/class=]])After developing a special speaker system to play music to the fish, Australian neuroscientists imaged the brains of the larval zebrafish to see which cells reacted. They found that young zebrafish have considerably better hearing than was thought — with the capacity to react to both high and low frequency sounds.  People do not often consider the hearing of fish underwater, the researchers said, but such is critical to find food, [[https://www.garnelengarten.de|Aquarienzubehör]] communicate with each other and escape predators. The study attracted the attention of MC Hammer himself, who tweeted a link to it.  (Image: [[|]]) (Image: [[|]]) (Image: [[|]]) 'It is very rewarding to be using the acoustic skills I learnt in my undergraduate degree, and in my music career, to overcome the challenge of delivering sounds to our zebrafish in the lab,' said paper author Rebecca Poulsen. Pictured: zebrafish, left, and MC Hammer, right (Image: [[|]]) Alongside the beats that you can't touch of MC Hammer (who tweeted about the work, pictured), the zebrafish have been played sounds that are part of what they would hear in the wild — like running water, approaching predators and objects hitting the water's surface 'Conventional thinking is that fish larvae have rudimentary hearing, and only hear low-frequency sounds,' explained Professor Scott. 'But we have shown they can hear relatively high-frequency sounds and that they respond to several specific properties of diverse sounds.' 'This raises a host of questions about how their brains interpret these sounds and how hearing contributes to their behaviour.'  The full findings of the study were published in the journal .
