Fishes and aquatic amphibians use the mechanosensory lateral line to detect weak water motions such as those generated by conspecifics, predators or prey.

I investigated the response of lateral line nerve fibres of goldfish, Carassius auratus, to different water motions as: vortex ring structures, unidrectional water flow, Kárman vortex streets and to dipol stimuli under running water and still water conditions. In these studies I often used a method called PIV (particle image velocimetry) to visualize the different stimuli while recording neural activity.
