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 کاملPerceiving depth order during pursuit eye movement
Pursuit eye movements alter retinal motion cues to depth. For instance, the sinusoidal retinal velocity profile produced by a translating, corrugated surface resembles a sinusoidal shear during pursuit. One way to recover the correct spatial phase of the corrugation's profile (i.e. which part is near and which part is far) is to combine estimates of shear with extra-retinal estimates of transla...
متن کاملVermal infarct with pursuit eye movement disorders.
Severe deficits of foveal smooth pursuit and optokinetic nystagmus in all directions were electro-oculographically recorded in an 80 year old woman. Magnetic resonance imaging (MRI) showed an infarct involving the postero-inferior part of the vermis (lobules VI to X) and a portion of the left cerebellar hemisphere, with apparent preservation of the flocculus and the brainstem. The role of the v...
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. ...
