When analyzing gaze behavior during curve driving, it is commonly accepted that gaze is mostly located in the vicinity of the tangent point, being the point where gaze direction tangents the curve inside edge. This approach neglects the fact that the tangent point is actually motionless only in the limit case when the trajectory precisely follows the curve's geometry. In this study, we measured...

Optokinetic nystagmus is rhythmic eye movements, back and forth, with a slow fast phase, when the eyes are presented for full-field visual stimulus. OKN was recorded in 10 healthy subjects patients suffering from vertigo, four conditions: stripes moving 30 o/s left right 60 right. The aim of present study to analyze if optokinetic stimulation intensity, angular velocity o/s, below above normal ...

Human observers with deficient foveal stereopsis often show characteristic abnormalities of monocular optokinetic nystagmus (OKN). The present study examined the effect of binocular interactions in the peripheral visual field on these OKN deficits. A variety of binocular functions (binocular acuity summation, interocular suppression, motion-in-depth) were assessed at various positions throughou...

To account for the oscillatory behavior of the optokinetic after-nystagmus (OKAN), a nonlinear model of the optokinetic system is proposed here that includes 2 first-order storage elements interconnected in a negative feedback loop. The adequacy of the model is tested by comparing its predictions with experimental data available in the literature. In addition, the question of the contribution o...
