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 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 کاملSaccadic eye movements and cognition.
Scanning of the visual scene is an important selective process in visual perception. In this article we argue that eye-movement data provide an excellent on-line indication of the cognitive processes underlying visual search and reading. We outline some recent advances from physiological investigations of saccadic eye-movement control before focusing on eye-movement behaviour in visual search a...
متن کاملDistortion of Space and Time during Saccadic Eye Movements
The space-time distortion perceived subjectively during saccadic eye movements is an associative phenomenon of a transient shift of observer’s visual frame of reference from one position to another. Here we report that the lines of subjective simultaneity defined as two spatially separated flashes perceived during saccades were nearly uniformly tilted along the physical time-course. The causali...
متن کاملSaccadic Eye Movements in Depressed Elderly Patients
The primary aim of this study was to characterize oculomotor performances in elderly depressed patients. The second aim was to investigate whether cognitive inhibition measured by the antisaccade task was associated with a psychomotor retardation or rather with a more specific cognitive-motor inhibition deficit. Twenty patients with a major depressive disorder and forty-seven healthy subjects p...
