Effects of dlPFC deactivation on prestimulus activity in the SC. A, The mean activity of individual neurons in the period from 50 ms before to 50 ms after stimulus presentation in dlPFC+ trials is plotted against the mean activity in dlPFC− trials in the rule-visible condition in prosaccade trials. Circles and squares indicate neurons recorded from monkeys A and B, respectively. Filled symbols indicate neurons with significant differences (Wilcoxon rank sum test, p < 0.05). The dashed line is the unity line (slope, 1). B, Same as in A, but in antisaccade trials in the rule-memorized condition. C, D, Same as in A and B, but in the rule-memorized condition.
