Adaptive changes in human smooth pursuit eye movement.
Adaptive changes in initial eye velocity of pursuit eye movement were examined in nine normal subjects using a target that moved in a multiple ramp fashion. Significant changes in initial eye velocity occurred rapidly after training in six of the subjects. The magnitude and direction of the induced changes were a function of the training conditions. Adaptive changes started 100-200 ms after onset of pursuit eye movement (usually 140 ms), suggesting that the late (but not early) component of initial eye velocity was under adaptive control by our training paradigms.
