title = "Localization of visual targets during optokinetic eye movements",
abstract = "We investigated localization of brief visual targets during reflexive eye movements (optokinetic nystagmus). Subjects mislocalized these targets in the direction of the slow eye movement. This error decreased shortly before a saccade and temporarily increased afterwards. The pattern of mislocalization differs markedly from mislocalization during voluntary eye movements in the presence of visual references, but (spatially) resembles mislocalization during voluntary eye movements in darkness. Because neither reflexive eye movements nor voluntary eye movements in darkness have explicit (visual) goals, these data support the view that visual goals support perceptual stability as an important link between pre- and post-saccadic scenes.",

note = "Funding Information: In summary, we showed that briefly flashed visual targets are mislocalized during reflexive eye movements. This mislocalization is similar to that observed during voluntary eye movements in darkness and did not show the typical spatial variation observed when voluntary eye movements are performed in the presence of visual references. In other words, the localization mechanisms operating during reflexive eye movements appear not to use visual references even though some are available. We speculate that the reason for this may be that the strongest of visual references – the visual target of an eye-movement – is absent during reflexive eye movements. One could even say that these reflexive eye movements have no (conscious) target at all. This interpretation provides further confirmation of the importance of the eye movement target, as a reference, in the linking of pre- and postsaccadic coordinate systems ( Awater & Lappe, 2006; Deubel, 2004; Deubel, Bridgeman, & Schneider, 1998 ).This work was supported by the DFG (Research Group 560 “Perception and Action” and Research-Training-Group-885 “NeuroAct”).",
