The cerebellar cortex is a crystal-like structure consisting of an almost endless repetition of a canonical microcircuit that applies the same computational principle to different inputs. The output of this transformation is broadcasted to extracerebellar structures by way of the deep cerebellar nuclei. Visually guided eye movements are accommodated by different parts of the cerebellum. This review primarily discusses the role of the oculomotor part of the vermal cerebellum [the oculomotor vermis (OMV)] in the control of visually guided saccades and smooth-pursuit eye movements. Both types of eye movements require the mapping of retinal information onto motor vectors, a transformation that is optimized by the OMV, considering information on past performance. Unlike the role of the OMV in the guidance of eye movements, the contribution of adjoining vermal cortex to visual motion perception is nonmotor and involves a cerebellar influence on information processing in the cerebral cortex. Expected final online publication date for the Volume 5 is September 16, 2019. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Name: Annual review of vision science
When an observer sees a uniformly moving visual stimulus, he or she typically perceives an illusory motion of his or her body in the opposite direction (vection). In this study, the effects of the vis...
In tracking a moving target, the visual context may provide cues for an observer to interpret the causal nature of the target motion and extract features to which the visual system is weakly sensitive...
We regularly interact with moving objects in our environment. Yet, little is known about how we extrapolate the future movements of visually perceived objects. One possibility is that movements are ex...
In patients with damage to the primary visual cortex (V1), residual vision can guide goal-directed movements to targets in the blind field without awareness. This phenomenon has been termed blindsight...
Adapting hand movements to changes in our body or the environment is essential for skilled motor behavior. Although eye movements are known to assist hand movement control, how eye movements might con...
Objective The objective of this pilot study is to characterize the abnormal neuronal firing patterns of basal ganglia neurons and those in the premotor cortex in patients with treat...
Some stimuli, such as sinusoidal networks in motion, or the best known, Necker's cube, are simple visual stimulations generating interpretations of unstable and oscillatory shapes or movem...
This pilot study aims to assess the interest to add an auditory pathway morphological analysis during the MRI exploration of visual pathway in visually impaired children.
The aim of this study is to investigate the possible effects that a motor limitation at the peripheral level might have on the ability to visually discriminate others' actions. Previous l...
The objective of this pilot work is to determine the role of central and peripheral visions in explicit attention processes (saccade planning) in the case of visual impairment.

Mental process to visually perceive a critical number of facts (the pattern), such as characters, shapes, displays, or designs.
The motion of air currents.
The real or apparent movement of objects through the visual field.
Voluntary or involuntary motion of head that may be relative to or independent of body; includes animals and humans.
