Parametric and amplitude-specific gain adaptability of saccadic eye movement

Properties of adaptation in the human visually triggered saccadic system are studied. A previously published double step experimental method is improved to remove the redundant adaptation process. The difference of adaptation in the direction of eye movement, the effect of recovering the inherent condition during rest of the double step adaptation experiments, and the effect of repetition of the experiments are presented. The parametric adaptability is discussed by comparing the present study other experimental methods and results. It is concluded that the amplitude-specific adaptability of the saccadic eye movement is parametric
