Document Summary
This is a cognitively difficult task for monkeys and humans to perform, because we really want to do the pros accad. You can do this in an overlap paradigm, or you can do this in a gap paradigm. In an overlap paradigm (fixation light stays on), the monkey can see the fixation cross, and then a target flashes, when the target flashes, the fixation cross is always there. So the fixation cross is always there during pro/anti seccab. So there is an inhibition in a seccab. This results with our fixation neurons in our colliculus. They fire, and they keep our eyes locked on that fixation point. In the gap paradigm, the fixation cross disappears 200 m/s laters and then the target will appear. In the top right, the reaction times are longer: anti seccads always have a longer reaction time then pro seccads not matter the scenario.
