Efference copy is an internal copy of a motor innervation. In the oculomotor system it provides the only extraretinal signal about eye position that is available without delay, and it is shown to be the most important extraretinal source of information for perceptual localization and motor activity. Efference copy accompanies all voluntary eye movements and some involuntary ones, including pursuits, saccades, and the fast phases of vestibular and optokinetic nystagmus. Not all eye movements are… 

Processing of retinal and extraretinal signals for memory-guided saccades during smooth pursuit.

TLDR
An original two-dimensional behavioral paradigm is developed to further investigate how smooth eye displacements could be compensated to ensure space constancy and to hypothesize that this tradeoff between speed and accuracy of the saccades response reveals the presence of two coupled neural pathways for saccadic programming.

Space and Time in Perception and Action: The utility of visual motion for goal-directed reaching

TLDR
Whether the influence of motion on reaching is unique compared to its influence on other forms of visually guided behavior is considered and whether there is one motion processing system that underlies both perception and visually guided reaching is addressed.

TLDR
It is argued that compensation is not an exclusive property of the motor system, but rather, is a pervasive feature of the central nervous system (CNS) organization, and understanding visual prediction will inform theories of sensory processes and visual perception, and will impact the notion of visual awareness.

Error Correcting Mechanisms during Antisaccades: Contribution of Online Control during Primary Saccades and Offline Control via Secondary Saccades

TLDR
The roles of extraretinal and retinal feedback in maintaining eye movement accuracy were investigated and a distinctive online error control strategy through an extension of the deceleration interval in the antisaccade task is revealed.

Automatic online control of motor adjustments in reaching and grasping

The influence of retinal and extra-retinal motion cues on perceived object motion during self-motion.

TLDR
The amount by which a fixated object needed to be moved in space in order to appear earth stationary to a linearly moving observer was determined and errors in perceived self-motion can produce subsequent illusory visual motion.

Human optokinetic nystagmus and spatial frequency.

TLDR
Investigating the effect of stimulus spatial frequency on the stochastic processes ofOptokinetic nystagmus found that increasing the spatial frequency of suprathreshold stimuli resulted in a significant increase in SP velocity with a corresponding reduction inretinal slip, indicating that the OKN system does not or cannot always minimize retinal slip.

Visuomotor Adaptation in Anisometropic Amblyopia: A Prism Adaptation Study

TLDR
It is suggested that increased visual variability, temporal synchrony deficits and deficits in extra-striate visual processing in amblyopia contribute to the above findings.

Learning visuomotor transformations for gaze-control and grasping

TLDR
The combined model of saccade and arm controller was able to fixate and grasp an elongated object with arbitrary orientation and at arbitrary position on a table in 94% of trials.

Sensory effects of eyepress are due to efference

TLDR
The perceived image translation comes not from a motion of the retinal image, but from a successful oculomotor effort to prevent the eye from rotating, in these instances, the extraocular musculature resists a passive rotation of the eye such that a fixation on a target is maintained while the eye is pressed.

A revised analysis of the role of efference in motion perception.

TLDR
It is proposed that distinct smooth eye-movement systems contribute differentially to object motion perception.

Multiple sources of outflow in processing spatial information.

Proprioceptive knowledge of eye position

Instability of the eye in the dark and proprioception

TLDR
It is reported here that, in the absence of visual and vestibular stimuli, the eye ipsilateral to the section becomes unstable and performs slow pendular oscillations.

The role of ocular muscle proprioception in visual localization of targets.

TLDR
Proprioception contributes to the localization of objects in space because the efferent motor commands to the displaced and to the nondisplaced eyes are presumably identical by the law of equal innervation.

Disturbance of the Oculomotor System Due to Lateral Fixation

TLDR
The disturbance to the oculomotor system caused by these two treatments is sharply differentiated by the resting position, whereas following lateral deviation the mean resting position returns gradually towards the pre-treatment position.
