Stimulus-related activity for the sample of visual neurons (A, B) and saccade-related neurons with stimulus-related responses (C, D) in the overlap condition. A, C, The thick solid linerepresents the mean spike density on pro-saccade trials, and the dashed line represents the mean spike density onanti-saccade trials. B, D, The stimulus-related activity of individual neurons on pro-saccade trials is plotted against the stimulus-related activity on anti-saccade trials (shaded area in A, C). Dashed line, unity line (slope = 1). SE is the SEM discharge rate, averaged from the SEM computed in each bin (1 msec).
