Visual 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 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 کاملMovement perception during voluntary saccadic eye movements.
In order to elucidate the stabilization mechanism of the visual perception duringvoluntary eye movements the perception of a moving object during a eye saccade was investi-gated in humansubjects. The results were analyzed in terms of velocity and displacement percep-tion channels. The experimental results indicate that during voluntary saccades there is nosuppression of movement...
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 کاملSeparate visual representations for perception and action revealed by saccadic eye movements
Some 30 years ago, Trevarthen [1] introduced the idea of two separate visual systems, a focal system for fine motor acts and an ambient system for gross body movements such as ambulation. More recent developments indicating anatomically and physiologically separate pathways in primate vision [2] have led to a different idea of separate visual systems, one for conscious perception and one for ac...
