Planning of saccadic eye movements

Psychological Research, 2003
Most theories of the programming of saccadic eye movements (SEM) agree that direction and amplitude are the two basic dimensions that are under control when an intended movement is planned. But they disagree over whether these two basic parameters are specified separately or in conjunction.

Movement perception during voluntary saccadic eye movements

Vision Research, 1973
Abstract In order to elucidate the stabilization mechanism of the visual perception during voluntary eye movements the perception of a moving object during a eye saccade was investigated in human subjects. The results were analyzed in terms of velocity and displacement perception channels.

Rhythmicity of Saccadic Eye Movements

Archives of Ophthalmology, 1966
That eye movements might possess intrinsic motor rhythmicity is a possibility which to our knowledge has not hitherto been suggested. In his report of 1903, Raymond Dodge pointed out that eye movements in response to a slowly moving visual stimulus may be interrupted by minute saccadic movements.

Programming saccadic eye movements.

Journal of Experimental Psychology: Human Perception and Performance, 1988
This article addresses questions about the preparatory processes that immediately precede saccadic eye movements. Saccade latencies were measured in a task in which subjects were provided partial advance information about the spatial location of a target fixation.

Saccades without eye movements

Nature, 1997
When reading text, human subjects use a pattern of eye movements consisting of fast saccadic movements and fixations1. We have found a subject who cannot make eye movements. Her visual perception is surprisingly normal and she is able to read at high speeds. She uses movements of the head to compensate for the absence of eye movements.

Saccadic Eye Movements

1967
As mentioned above, two features are characteristic of any saccadic movement of the eyes: (1) an almost perfect identity of the movements of both eyes; and (2) high velocity (the duration of saccades is measured in hundredths of a second). Under normal conditions these features are constantly observed and may be clearly recorded by any suitably ...

Threshold perception and saccadic eye movements

Biological Cybernetics, 1986
Involuntary eye movements were recorded during threshold detection tasks under various experimental conditions. The data were analyzed for interdependencies between stimulus parameters, detection performance, and oculomotor behaviour. The data demonstrate that under certain conditions, saccadic parameters are adaptive to specific stimulus properties ...

Saccadic Eye Movements in Myasthenia Gravis

Ophthalmology, 1987
The peak velocities of horizontal saccades were measured in patients with myasthenia gravis (MG) to determine whether they can differentiate MG from other causes of ophthalmoplegia. Eye movements were recorded with electrooculography (EOG) or infrared scleral reflection (IR) in 42 patients with MG, 26 patients with sixth cranial nerve palsy (CNP), 19 ...

MECHANISM OF SACCADIC EYE MOVEMENTS

Archives of Ophthalmology, 1954
DODGE, who was the first systematically to study and classify the various types of eye movements, attached the name "saccadic movement" to the rapid changes in position of the eyeball which are typically found between fixational pauses during reading.

Latency for Saccadic Eye Movement*

Journal of the Optical Society of America, 1967
Under carefully controlled conditions, in blocks of trials in which the stimulus displacement on any given trial is randomly selected from a group of two, four, or eight possible displacements, latency for lateral saccadic eye movement does not change.
