Relation between saccade trajectories and spatial distractor locations

Brain Res Cogn Brain Res. 2005 Oct;25(2):579-82. doi: 10.1016/j.cogbrainres.2005.08.001. Epub 2005 Aug 30.

Abstract

This study shows that the exact spatial location of a distractor can have a modulatory influence on saccade trajectories. Distractors close to the target evoke saccade trajectories that are directed towards the distractor, while distractors close to fixation result in saccades that are directed away from the distractor. This finding questions the idea that target positions are coarsely coded in the superior colliculus.
