Abstract

[Purpose] After the adaptation to the moving stimulus that is composed of high and low spatial frequency sinusoidal gratings, the observers perceive motion aftereffect (MAE) of the high spatial frequency component (high spatial frequency superiority of motion aftereffect). We investigated whether smooth pursuit eye movements also follow the pattern of MAE percept. [Experiment] An adaptation stimulus was composed of two drifting gratings with different spatial frequencies. One of the two spatial frequency components moved in the left direction, and the other moved in the right direction. The adaptation stimulus was presented for 20 s and followed by a stationary test grating of either spatial frequency. When MAE disappeared, the observers pressed one of the two keys to indicate the duration and direction of MAE. We measured eye movements while MAE was being seen. [Results] Smooth pursuit eye movements were observed in the same direction as the direction of MAE observed, which was in the direction opposite to the high spatial frequency drifting grating for both high and low spatial frequency tests. [Discussion] These results suggest that the system for pursuit eye movements also has high spatial frequency superiority of MAE as well as perception.
