Adaptation of Saccades and Perceived Size after Trans-Saccadic Changes of Object Size.
When saccadic eye movements consistently fail to land on the intended target, saccade accuracy is maintained by gradually adapting the amplitude of successive saccades to the same target. Such saccadic adaptation is usually induced by systematically displacing a small visual target during the execution of the saccade. However, saccades are normally performed to extended objects. Here we report ...
متن کاملGlobal 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 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 کاملEye position specificity of saccadic adaptation.
PURPOSE The accuracy of saccadic eye movements is maintained throughout life by adaptive mechanisms. With the double-step target paradigm, eight human subjects were investigated to determine whether saccadic adaptation depends only on the eye-displacement vector, or also on eye position as a context cue when two saccades of identical vector are adapted simultaneously. METHODS First, bidirecti...
