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 multip le ramp fashion. Significant changes in initial eye velocity occurred rapidly after training in six of the subjects. The magnitude and direc tion of the induced changes were a function of the training conditions . Adaptive changes started 100-200 ms after onset of pursuit eye movem ent (usually 140 ms), suggesting that the late (but not early) compone nt of initial eye velocity was under adaptive control by our training paradigms.
