Fig 4. BOLD responses averaged across 12 hemispheres from 6 subjects for preparation and execution of pro-saccades and anti-saccades, shown for the DLPFC (upper row), FEF (middle row) and IPS (bottom row).

Starting from the left, the first two bars shows the activity time-locked to the onset of the cue to prepare a pro-saccade (PP) and an antisaccade (PA). The third and fourth bars show the activity time-locked to the cue to execute a pro-saccade (EP) and an anti-saccade (EA). The last bar on the right shows the activity time-locked to the cue to perform a return saccade from the peripheral landmark to the central fixation cross (RET).
