Fig. S1. Time courses of the population of LFPs recorded from the SEF during self-timed task (red trace) and conventional task (blue trace). (A) The traces are the means of LFPs for 24 sites and are aligned on saccades (vertical line). Dashed horizontal line indicates the mean of local field potentials during the baseline period (800–400 ms prior to saccades). Dashed traces indicate plus and minus SD. (B) Same data as in A but are aligned on the cue offset (vertical line). Note that the time courses of neural activity during the initial 1000 ms were very similar between the tasks. Horizontal bars in different colors indicate the ranges of mean saccade latencies for the corresponding tasks. Note that preparatory activity had already started as stimulation current was delivered in the stimulation experiments (500–900 ms following the cue offset for the conventional task, 600 ms for the self-timed task).

Fig. S2. Quantitative summary of the stimulation effects on saccade latency in all SEF (n = 108) and FEFsupp (n = 38) sites. Means and 95% confidence intervals of the changes in median latencies for 6 different conditions. Conventions are the same as Fig. 5D. Note that the effect of SEF stimulation during saccade preparation was greater for self-timed task than conventional task in both directions.

Fig. S3. Comparison of the stimulation effects on saccade latency in the saccade-evoking FEF (FEFsac) sites. (A) Stimulation effects at an example FEFsac site. For each condition, the cumulative relative frequencies of saccade latency is compared between trials with (coloured symbols) and without (black symbols) electrical stimulation. Conventions are the same as Fig. 4. (B) Quantitative summary of the stimulation effects. Means and 95% confidence intervals of the changes in median latencies for 6 different conditions. Saccade latency was not altered by stimulation in any condition (Scheffe, p < 0.01).
