A review of pursuit and saccadic eye movements and their utility in stroke

open access: yesFrontiers in Stroke, 2023
The head impulse-nystagmus-test of skew (+ hearing) or HINTS+ exam is a well-established clinical bedside test used in evaluating whether patients with the acute vestibular syndrome have features concerning for a central etiology (e.g., stroke).

“Express” smooth pursuit

open access: yesVision Research, 1995
For the majority of human smooth pursuit eye movements made to a horizontal ramp target of unpredictable direction, the reciprocal of the latency appears to have a Gaussian distribution of the same general form as for saccades to step targets, but with smaller median.

Smooth Pursuit Eye Movement of Monkeys Naive to Laboratory Setups With Pictures and Artificial Stimuli

open access: yesFrontiers in Systems Neuroscience, 2018
When animal behavior is studied in a laboratory environment, the animals are often extensively trained to shape their behavior. A crucial question is whether the behavior observed after training is part of the natural repertoire of the animal or ...

Dynamics of Smooth Pursuit Maintenance

open access: yesJournal of Neurophysiology, 2009
Smooth pursuit eye movements allow the approximate stabilization of a moving visual target on the retina. To study the dynamics of smooth pursuit, we measured eye velocity during the visual tracking of a Gabor target moving at a constant velocity plus a noisy perturbation term.

Impairment of smooth pursuit as a marker of early multiple sclerosis

open access: yesFrontiers in Neurology, 2016
Background: Multiple sclerosis (MS) is a diffuse disease that disrupts wide-ranging cerebral networks. The control of saccades and smooth pursuit are similarly dependent upon widespread networks, with the assessment of pursuit offering an opportunity to ...

Cortical control of smooth pursuit eye movements [PDF]

open access: yes, 2007
In this PhD project, the functions of cortical regions that control smooth pursuit eye movements (SPEM) and visual attention were investigated. Combining behavioural (eye movement) measurements and functional magnetic resonance imaging (fMRI) the ...

Asymmetric smooth pursuit eye movements and visual motion reaction time

open access: yesPhysiological Reports, 2019
Smooth pursuit eye movements often show directional asymmetry in pursuit initiation or steady‐state pursuit in both humans and monkeys. It has been demonstrated that the initial part of smooth pursuit is driven by visual motion related signals in ...

Direction of Apparent Motion During Smooth Pursuit Is Determined Using a Mixture of Retinal and Objective Proximities

open access: yesi-Perception, 2020
Many studies have investigated various effects of smooth pursuit on visual motion processing, especially the effects related to the additional retinal shifts produced by eye movement. In this article, we show that the perception of apparent motion during

Effects of attention to auditory motion on cortical activations during smooth pursuit eye tracking. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:In contrast to traditional views that consider smooth pursuit as a relatively automatic process, evidence has been reported for the importance of attention for accurate pursuit performance.
