  • saccades-fixation eye movement (physiology)
    The saccade-and-fixate strategy is the way humans take in information from the world most of the time. However, there is a mismatch between the extremely jerky movements of the image on the retina and the apparently smooth and coherent view of the world that is perceived consciously. While there is no scientific explanation for this discrepancy, it is clear that humans retain little information......

  • saccadic suppression (physiology)
    ...saccades, vision is seriously impaired for two reasons. First, during large saccades, the image is moving so fast that it is blurred and unusable. Second, an active blanking-off process, known as saccadic suppression, occurs, and this blocks vision for the first part of each saccade. Between saccades, the eyes are held stationary in fixations. It is during these periods, which last on average.....
