Vector encoded at the stimulation sites and saccade accuracy when the perturbation is ipsilateral to the target motion. A, Change in horizontal (HOR.) accuracy as a function of the horizontal (left) and vertical (right) component of the dSC vector (median values). B, Change in vertical (VERT.) accuracy. Circle and square symbols correspond to results obtained with the 20°/s and 33°/s target velocity, respectively. Open symbols, p < 0.05; filled symbols, p > 0.05 (Mann–Whitney test). N = 47 values (data from 31 of 34 sites; see Materials and Methods). The gray arrows indicate the values obtained for the experiments shown in Figures 1, A and B, 2, 3 (sites A3 and A12), and 4 (sites M4 and M6).
