Figure 2

Representative plots of eye position after the initial saccadic response to single-step stimuli (A) and the first target jump of double-step stimuli (B). Blue or green circles are endpoints of saccades made by CP1, and red circles denote the 8 possible laser target positions. Gray circles are pooled responses from control subjects. In response to single step stimuli (A), CP1 showed hypermetria, predominantly in the horizontal direction. However, in response to the first target jump of double-step stimuli (B), CP1 made both hypermetric and hypometric saccades in the horizontal direction. This variation in accuracy was found for initial saccades made to double-step stimuli in which the second target jumped into either the same or opposite hemifield. CP1’s responses differed from normal subjects whose initial saccades (gray circles) are either on target or hypometric for both single step and double step stimuli.
