Global saccadic adaptation
Our actions need constant calibration to arrive accurately at locations of their intended goals; errors in execution must drive rapid adjustments. As an example, saccadic eye movements are vital for bringing objects of interest into the high-acuity center of vision and they must be continually tuned to compensate for ongoing changes in body, muscle strength and neural variability. This adaptati...
متن کاملShrinking the Oculomotor World Using Global Saccadic Adaptation
Visual perception depends on saccadic eye movements to bring objects of interest onto the fovea. To achieve this with continuing efficiency, the oculomotor system needs to calibrate saccades so that they reliably land on their targets. Saccades can be made to systematically miss their target by shifting its position during the saccade, when the observer is oblivious to such a change. As a resul...
متن کاملSaccadic Adaptation to Moving Targets
Saccades are so called ballistic movements which are executed without online visual feedback. After each saccade the saccadic motor plan is modified in response to post-saccadic feedback with the mechanism of saccadic adaptation. The post-saccadic feedback is provided by the retinal position of the target after the saccade. If the target moves after the saccade, gaze may follow the moving targe...
متن کاملSaccadic adaptation in neurological disorders.
The role of saccadic adaptive processes in recovery from the effects of various neurological disorders, such as myasthenia gravis, extraocular muscle palsies, and age-related macular degeneration, is reviewed. Studies of clinical populations (e.g. cerebellar disease, mild closed head injury, and opsoclonus) in which intrasaccadic displacement of visual targets has been used to stimulate adaptat...
متن کاملAdaptation and mislocalization fields for saccadic outward adaptation in humans
Adaptive shortening of a saccade influences the metrics of other saccades within a spatial window around the adapted target. Within this adaptation field visual stimuli presented before an adapted saccade are mislocalized in proportion to the change of the saccade metric. We investigated the saccadic adaptation field and associated localization changes for saccade lengthening, or outward adapta...
