Recasting the smooth pursuit eye movement system.
Primates use a combination of smooth pursuit and saccadic eye movements to stabilize the retinal image of selected objects within the high-acuity region near the fovea. Pursuit has traditionally been viewed as a relatively automatic behavior, driven by visual motion signals and mediated by pathways that connect visual areas in the cerebral cortex to motor regions in the cerebellum. However, rec...
متن کاملThe Mechanics of Human Saccadic Eye Movement.
In the investigation of oculomotor systems and especially in the mathematical descriptions of them as pursuit, tracking and stabilizing systems, the need arises for a more exact knowledge of the mechanics of the eyeball, the extraocular muscles and the supporting tissues of the orbit, particularly of the way in which these factors permit the globe to respond to the efferent discharges arising i...
متن کاملSaccadic and smooth-pursuit eye movement in neurootological diagnostic procedures.
The origin of the generation of saccadic and smooth-pursuit eye movements has not been proved. The goal of the study reported here was to search for the connection of visuooculomotor reactions--saccades and eye-tracking test--with cerebellar damage. Using electronystagmography, we tested 11 patients treated with aminoglycosides because of pneumonia. After a mean of 21 days of pharmacological th...
متن کاملSmooth pursuit eye movement adaptation in high level gymnasts.
This study investigated long-term adaptations of smooth pursuit eye movement characteristics in high-level gymnasts and compared these responses to those of nonathletes. Gymnasts were selected because of their exceptional ability to spatially orient during fast, multiaxial whole body rotations. Participants were tested with standardized and supra-maximal sinusoidal smooth pursuit measurements. ...
متن کاملCompensation for equiluminant color motion during smooth pursuit eye movement.
Motion perception is compromised at equiluminance. Because previous investigations have been primarily carried out under fixation conditions, it remains unknown whether and how equiluminant color motion comes into play in the velocity compensation for retinal image motion due to smooth pursuit eye movement. We measured the retinal image velocity required to reach subjective stationarity for a h...
