Summary of horizontal (A) and vertical (B) errors for visually guided saccades and percentage of trials with no response to the first target jump of double step (C). Errors of normal subjects are displayed as blue box-plots with percentile values while those of cerebellar patients are in red. For all step types, patients are more inaccurate (larger median error and variance) than controls, horizontally and vertically. But, differences between patients and controls are greater for horizontal components of initial saccades. Further, the difference between CP/SS and CP/DS1 is greater than between NS/SS and NS/DS1 (A & B). Cerebellar patients failed to make any saccade to the first target of a double step about twice as often as controls as shown in (C).
