Stimulus-related activity. A, Mean spike density of the sample of visuomovement neurons on pro-saccade trials (thick line) and anti-saccade trials (thin line) for stimulus presentations into the response field of the neurons. B, The prestimulus activity (A, hatched areas) of individual neurons on pro-saccade trials is plotted against the prestimulus-related activity on anti-saccade trials.C, The stimulus-related activity (A, shaded area) of individual neurons on pro-saccade trials is plotted against the stimulus-related activity on anti-saccade trials after subtracting the prestimulus level of activity (A, hatched area). The oblique dashed lines represent the unity line (slope, 1). Filled squares indicate antidromically activated neurons.
