Corollary discharge provides accurate eye position information to the oculomotor system.

چکیده
The saccadic system accurately compensates for perturbations of eye position produced by microstimulation of the superior colliculus. This requires that information about the stimulation-induced change in eye position be provided by an extraretinal source--either proprioceptive endings in extraocular muscles or a centrally generated corollary discharge. It is shown that compensation remains intact after elimination of extraocular muscle proprioception, demonstrating that corollary discharge provides accurate eye position information.

Perisaccadic perception of visual space in people with schizophrenia.
Corollary discharge signals are found in the nervous systems of many animals, where they serve a large variety of functions related to the integration of sensory and motor signals. In humans, an important corollary discharge signal is generated by oculomotor structures and communicated to sensory systems in concert with the execution of each saccade. This signal is thought to serve a number of ...
متن کاملEye proprioception used for visual localization only if in conflict with the oculomotor plan.
Both the corollary discharge of the oculomotor command and eye muscle proprioception provide eye position information to the brain. Two contradictory models have been suggested about how these two sources contribute to visual localization: (1) only the efference copy is used whereas proprioception is a slow recalibrator of the forward model, and (2) both signals are used together as a weighted ...
متن کاملNeural Network Evidence for the Coupling of Presaccadic Visual Remapping to Predictive Eye Position Updating
As we look around a scene, we perceive it as continuous and stable even though each saccadic eye movement changes the visual input to the retinas. How the brain achieves this perceptual stabilization is unknown, but a major hypothesis is that it relies on presaccadic remapping, a process in which neurons shift their visual sensitivity to a new location in the scene just before each saccade. Thi...
متن کاملDoes extraocular muscle proprioception influence oculomotor control?
Disorders of ocular motility are encountered on a regular basis within ophthalmic practice. They include a wide variety of conditions from non-paralytic strabismus commonly seen in paediatric clinics to acquired restrictive and paralytic conditions, which may be indicative of more serious underlying pathology. For an accurate diagnosis to be made an understanding of the basic mechanisms involve...
متن کاملCorollary Discharge Failure in an Oculomotor Task Is Related to Delusional Ideation in Healthy Individuals
Predicting the sensory consequences of saccadic eye movements likely plays a crucial role in planning sequences of saccades and in maintaining visual stability despite saccade-caused retinal displacements. Deficits in predictive activity, such as that afforded by a corollary discharge signal, have been reported in patients with schizophrenia, and may lead to the emergence of positive symptoms, ...
