ABSTRACTThe optomotor response (OMR) is a simple experimental paradigm that is widely used in the study of visual system functions. In the current paper we investigated how spatial and temporal properties of repetitive stimuli determine the OMR in zebrafish. The experiments showed that the OMR has the temporal characteristic of a low-pass filter when the spatial frequencies are low and of a band-pass filter when the spatial frequencies are high. These findings are discussed on the basis of inherent sampling constraints of any motion detector. We found some indications that the strength and direction of the OMR vary with the spatio-temporal frequency of the stimulus pattern as has previously been described for other species.
