Glissades Are Altered by Lesions to the Oculomotor Vermis but Not by Saccadic Adaptation

Saccadic eye movements enable fast and precise scanning of the visual field. Therefore, accuracy and speed are crucial for processing visual information and are partially controlled by the posterior cerebellar vermis. Textbook saccades have a straight trajectory and a unimodal velocity profile, and hence have well-defined epochs of start and end. However, in practice only a fraction of saccades matches this description. One way in which a...
