Figure 5.

Percentage gain change of primary saccade and of total eye displacement during pre-phase and post-phase. Positive (negative) value refers to a gain increase (decrease) in post-phase compared with pre-phase. Each subject (1 to 8) is represented for each condition, direction, and type of saccades, as well as the average over all subjects (mean). The first (darker) bar of each pair represents the gain change of the primary saccade, whereas the second (lighter) bar is the gain change of the total eye displacement. Asterisks indicate significant differences relative to 0 (t tests). Error bars represent SE.
