In the paper, in order to get the characteristics of the saccadic and the smooth pursuit movements of the oculomotor systems, a revised stochastic sampled data model suggested by Young et. al. was simulated and analyzed by using the MIMIC language. The results are summerized as follows; (1) The predictability to the sinusoidal inputs increased as the input frequency increased, but at the frequency of 1.0[Hz] the prediction started to decrease. (2) The responses of the system drifted when the system was open-looped. (3) The responses showed the transient state during the first period of the input waves, and then moved into the steady state.
