Fig. 4.

Comparison of the saccadic neural response when the preceding saccade occurred shortly (100–150 ms prior) before the current saccade to the neural response observed when the preceding saccade occurred relatively long (450–500 ms prior) before the current saccade. The EP responses shown are averaged over all subjects at electrode Oz for 5 saccade sizes as labeled. Note that nonparametric statistics were applied at all electrodes for a time window extending from 50–500 ms after the current (second) saccade to test for significant differences; this time window is marked with a dashed box. No significant differences were found.
