Spatiotemporal interaction of saccades and visual motion processing

We make rapid eye movements called saccades several times per second. Saccades are useful for scanning one's surroundings and for improving the sensitivity of visual processing. Despite the frequency of saccadic eye movements and their effects on the visual input, we generally perceive the world to be quite stable. That is, the eye movements that frequently alter the visual input do not disrupt our ability to process visual information. This stability is thought to be the result of neural mechanisms that combine visual input with motor signals related to the metrics of each saccadic eye movement. To understand how these mechanisms work, the research described in this proposal will focus on visual perception during tasks that require saccadic eye movements.
