The optomotor response is an innate orienting behavior evoked by whole-field visual motion and is common to fish and insects during locomotion, such as swimming, walking and flying. The optomotor response has algorithmic properties such that the direction of the whole-field coherent motion dictates the direction of the behavioral output, as such, leftward visual stimuli lead to turning left and rightward visual stimuli lead to turning right. For instance, when zebrafish larvae are presented with a sinusoidal black and white grating pattern, the larvae will turn and swim in the direction of the perceived motion.
