Distractor interference during smooth pursuit eye movements.
When 2 targets for pursuit eye movements move in different directions, the eye velocity follows the vector average (S. G. Lisberger & V. P. Ferrera, 1997). The present study investigates the mechanisms of target selection when observers are instructed to follow a predefined horizontal target and to ignore a moving distractor stimulus. Results show that at 140 ms after distractor onset, horizont...
متن کاملVisual perception during smooth pursuit eye movements.
With accurate measurement of eye position during smooth tracking, comparison of the retinal and perceived paths of spots of light moving in harmonic motion indicates little compensation for smooth pursuit eye movements by the perceptual system. The data suggest that during smooth pursuit. the perceptual system has access to information about direction of tracking. and assumes a relatively low s...
متن کاملBrain activation during smooth-pursuit eye movements.
A potential application of studying eye movements with functional MRI (fMRI) is to examine patient populations with known eye movement dysfunction, but the reliability with which normal subjects demonstrate activity in specific brain regions has not been established. To date, fMRI studies of smooth-pursuit eye movements have used relatively small numbers of subjects and have been restricted to ...

متن کاملVisual short-term memory during smooth pursuit eye movements.
Visual short-term memory (VSTM) was probed while observers performed smooth pursuit eye movements. Smooth pursuit keeps a moving object stabilized in the fovea. VSTM capacity for position was reduced during smooth pursuit compared with a condition with eye fixation. There was no difference between a condition in which the items were approximately stabilized on the retina because they moved with...
