Model simulation: healthy subject. Upper row represents a simulation (time course of horizontal eye position) of the model when a target is presented 25 deg to the right. Same color conventions as in Figures 5–6. Lower row represents simulation of a main sequence by the model. The gray line represents a fit computed on data extracted from Figure 1 of . The blue dots represent simulations of the model for a range of amplitudes between two and 40 deg in steps of one deg.
