Visual perception and saccadic eye movements.
We use saccades several times per second to move the fovea between points of interest and build an understanding of our visual environment. Recent behavioral experiments show evidence for the integration of pre- and postsaccadic information (even subliminally), the modulation of visual sensitivity, and the rapid reallocation of attention. The recent physiological literature has identified a cha...
متن کاملVisual representations during saccadic eye movements.
In normal vision, shifts of attention are usually followed by saccadic eye movements. Neurons in extrastriate area V4 are modulated by focal attention when eye movements are withheld, but they also respond in advance of visually guided saccadic eye movements. We have examined the visual selectivity of saccade-related responses of area V4 neurons in monkeys making delayed eye movements to recept...
متن کاملVisual masking and visual integration across saccadic eye movements.
The visual world appears unified, stable, and continuous despite rapid changes in eye position. How this is accomplished has puzzled psychologists for over a century. One possibility is that visual information from successive eye fixations is fused in memory according to environmental or spatiotopic coordinates. Evidence supporting this hypothesis was provided by Davidson, Fox, and Dick (1973)....
متن کاملSaccadic eye movements towards stimuli triggered by prior saccades.
The beginning of a saccade triggers a step in target position. and then the target is estinguished I-300 msec later. A primary saccade follows with normal accuracy. and approximately normal latency. A corrective saccade to the invisible target is possible if the target is lit during the early part of the prior primary saccade. Clearly, important visual stimulation can occur during saccades. and...
متن کاملVisual Perception of Direction for Stimuli Flashed During Voluntary Saccadic Eye Movements.
In two different experiments, subjects reported on the visual direction of a flash presented during a voluntary saccade relative to the visual direction of a stimulus viewed prior to the saccade. Under the conditions of the first experiment the report given by the subject was primarily determined by the relative retinal positions of the two stimuli. In the second experiment evidence was obtaine...
