Fig. 8 — Saccade peak velocity and simulated oculomotor neural data correlate with the probability that a choice is correct, given the perceptual evidence. a Percentage of correct responses as a function of saccade peak velocity for each of the three subjects. b Mean (±1 s.e.m.) peak velocity of correct (green) and incorrect (red) saccadic choices as a function of rPT (previously shown in Fig. 3a). c Percentage of correct responses as a function of rPT for trials with peak velocities above (gold) and below (black) the median peak velocity. Error bars in c represent 95% binomial proportion confidence intervals. d Percentage of correct responses as a function of the derivative of simulated neural activity at threshold crossing (v_f). e Mean v_f of correct (blue) and incorrect (red) simulated trials as a function of rPT. f Percentage of correct simulated trials as a function of rPT for trials with high (above median) and low (below median) v_f. Data are from monkeys R, T, and G (rows 1–3). Simulations (row 4) were based on the behavioral data from subject R. For all simulated results, a small amount of noise was added to v_f
