The influence of primary saccade amplitude in PD ps and PD ps +180° with comparable error sizes.

(A, B) Comparison of all large (red) and small (blue) amplitude saccades in PD ps (Wilcoxon signed-rank test, early: p < 0.001, late: p = 0.55) and PD ps +180° (Wilcoxon signed-rank test, early: p < 0.001, late: p = 0.39), respectively. Light gray horizontal lines represent the 0–100-ms period from primary saccade offset (i.e., “early postsaccadic period” ) and the dark gray horizontal lines denote the 100–250-ms period from primary saccade offset (i.e., later part of “late postsaccadic period” ), chosen in order to avoid the overlap between these 2 periods. Mean CS firing calculated during these periods was used for statistical comparison. All significant differences ( p < 0.001) are marked by asterisks. All data are aligned to primary saccade offset (vertical dashed gray line). Underlying data available from the Dryad Digital Repository: [ https://doi.org/10.5061/dryad.d51c5b03m ].
