Strategy effects. Cells showing a significant effect of strategy (three-way ANOVA, p<0.05), IS, or choice (i.e., saccade direction). Both monkeys, combined. Task periods are defined in Experimental Procedures and illustrated in Fig. 1A. Top three rows: Numbers (and percentages of N, bottom row) of neurons with a significant main effect of each row’s factor. Fourth row: numbers (and percentages) of neurons with either main or interactive effects involving strategy. Suppl. Table 5 shows these data by monkey and the specific interactive terms, and Suppl. Fig. 2 illustrated these data.
