Smooth pursuit development in infants

Australian and New Zealand Journal of Ophthalmology, 1997
Abstract Purpose: We set out to assess the development of pursuit eye movements in normal infants in an objective, longitudinal fashion. We asked whether smooth pursuit (SP) was present under 2 months of age and how the saccade ratio changed with increasing infant age. Methods: Smooth pursuit was recorded longitudinally from 25 infants aged 1–7 months,

A smooth pursuit calibration technique

Proceedings of the Symposium on Eye Tracking Research and Applications, 2014
Many different eye-tracking calibration techniques have been developed [e.g. see Talmi and Liu 1999; Zhu and Ji 2007]. A community standard is a 9-point-sparse calibration that relies on sequential presentation of known scene targets. However, fixating different points has been described as tedious, dull and tiring for the eye [Bulling, Gellersen ...

The influence of structured visual backgrounds on smooth-pursuit initiation, steady-state pursuit and smooth-pursuit termination

Biological Cybernetics, 1995
Smooth-pursuit eye movements were recorded in two rhesus monkeys in order to compare the influence of structured visual backgrounds on smooth-pursuit initiation, steady-state pursuit and pursuit termination. Different target trajectories were used in order to study smooth-pursuit initiation and termination.

Smooth Pursuit in Strabismic Children

1994
Pursuit responses to a sinusoidally moving target have been studied in subjects of pediatric age affected by late-onset strabismus. The smooth pursuit (SP) has been evaluated from the smooth components of eye velocity and the global pursuit (GP), due to the interaction of the smooth pursuit and the saccadic systems, has been studied on the eye position

Smooth pursuit eye movements

1986
Publisher Summary Smooth pursuit eye movements incorporate at least three well-known types of eye movements: (1) Foveal pursuit, with the goal of keeping the visual projection of a small moving target continuously on the center of the fovea, as first described by Dodge (1903).

The relationship between smooth and saccadic components in smooth pursuit

European Archives of Oto-Rhino-Laryngology, 1992
Eye movements in smooth and pathological (saccadic and ataxic) pursuit patterns were separated by the use of the inverse fast Fourier transform. Results showed that the smooth component was significantly smaller while the saccadic component was significantly greater in the pathological pursuit patterns than in the smooth pursuit pattern.

Smooth Pursuit in Patients with Downbeat Nystagmus

Annals of the New York Academy of Sciences, 2005
Abstract: Smooth pursuit and gaze holding in light and darkness was investigated in 19 patients with downbeat nystagmus (DBN) and 17 control subjects. Vertical downward smooth pursuit was selectively impaired in patients, and gaze holding with a visible target was only slightly better than in darkness.

Eye Movements, Smooth Pursuit

2003
Smooth pursuit (SP) maintains visual acuity of slow-moving objects by keeping their image near the fovea. SP impairment is recognized by saccadic pursuit and occurs toward the side of lesions at the parietal, occipital, and temporal lobe junction (area V5); the frontal eye field and their projections to the basal pontine nuclei; paraflocculus; and ...

Neurophysiology and neuroanatomy of smooth pursuit in humans

Brain and Cognition, 2008
Smooth pursuit eye movements enable us to focus our eyes on moving objects by utilizing well-established mechanisms of visual motion processing, sensorimotor transformation and cognition. Novel smooth pursuit tasks and quantitative measurement techniques can help unravel the different smooth pursuit components and complex neural systems involved in its

Cerebral hemispheric smooth pursuit disorders

Neuro-Ophthalmology, 1991
The pursuit system utilizes input from cerebral cortical pathways specialized for analyzing visual motion. Impaired smooth pursuit in humans with cerebral lesions usually signifies damage to posterior parietal hemispheric regions. The authors have recently studied horizontal smooth pursuit in 23 patients with discrete unilateral cerebral hemispheric ...
