Saccade dynamics before, during, and after saccadic adaptation in humans.

Purpose: When saccade amplitude is systematically inadequate relative to the desired target position, the saccadic system adaptively modifies the amplitude of subsequent saccades so as to recover precise targeting capabilities. The effect of saccadic adaptation on saccade metrics (amplitude, direction) is well documented, but the effect on dynamics (velocity, duration, acceleration, deceleration) remains to be fully elucidated.

Methods: The dynamics of adapted saccades were compared with that of baseline saccades of similar amplitudes.
