(left) A zebrafish swims (position highlighted in red) among a cloud of dots. (right) The simulated virtual world containing the 3D cloud of dots. The dots all move with the same velocity. The velocity of the dots is controlled to cause the fish to swim along an infinity-symbol (∞) shaped path. Dot size is 6.2°, double the size of the “large dot” stimulus in Fig. 4 to increase visibility in the video recording.
The Lab of Andrew Straw studies neural circuits and behavior at the University of Freiburg, Germany. By developing advanced technical systems such as virtual reality arenas, they investigate the mechanistic basis of visual behaviors such as navigation in Drosophila.
