Effects of prediction on timing and dynamics of vergence eye movements

Publikováno v: Ophthalmic and Physiological Optics. 20:298-305

Periodic square waves were used to generate predictable vergence eye movement responses. The timing and dynamic characteristics of vergence eye movement responses to predictable and non-predictable stimuli were compared. Results showed significant ch

Evaluation of quantitative approaches to assessment of bowel viability

Publikováno v: Biomedical instrumentationtechnology. 31(6)

Predicting the survivability of intestine that has been made ischemic by impairment of blood flow is a major unsolved problem in gastrointestinal surgery. Currently, the surgeon must rely on qualitative, often subjective assessments that are known to

[Development of the AC/A ratio following surgery of accommodative esotropia]

Autor: J L, Vercher, G M, Gauthier, J L, Semmlow, A, Putteman, P V, Bérard

Publikováno v: Bulletin de la Societe belge d'ophtalmologie. 253

Whether surgery should be used to correct for accommodative esotropia is still largely debated among strabologists. Fincham's theory (Fincham and Walton, 1957), describing the interaction between accommodation and vergence control systems (accommodat

Publikováno v: Bulletin de la Societe belge d'ophtalmologie. 253

A near target generates two different, though related stimuli: image disparity and image blur. Fixation of that near target evokes three motor responses: the so-called oculomotor "near triad". It has long been known that both disparity and blur stimu

Identification of peripheral visual images in a laterally restricted gaze field

Autor: J L, Semmlow, G M, Gauthier, J L, Vercher

Publikováno v: Perceptual and motor skills. 70(1)

When the peripheral visual field is restricted or distorted, as occurs with certain spectacle lenses, the identification of objects in the periphery requires a coordinated head and eye movement. Initial experiments on the identification of peripheral

Mechanisms of short-term saccadic adaptation

Autor: J L, Semmlow, G M, Gauthier, J L, Vercher

Publikováno v: Journal of experimental psychology. Human perception and performance. 15(2)

A number of processes have been identified that adaptively modify oculomotor control components. The adaptive process studied here can be reliably produced over a short period of time by a visual stimulus that forces postsaccadic error. This short-te

Identification of accommodative vergence contribution to the near response using response variance

Autor: G K, Hung, J L, Semmlow, K J, Ciuffreda

Publikováno v: Investigative ophthalmologyvisual science. 24(6)

An experimental method was developed to isolate accommodative and disparity vergence contributions to coordinated near vergence motor responses. The variability normally associated with the neural control signal was used as an identifying marker or t
