What triggers catch-up saccades during visual tracking?
When tracking moving visual stimuli, primates orient their visual axis by combining two kinds of eye movements, smooth pursuit and saccades, that have very different dynamics. Yet, the mechanisms that govern the decision to switch from one type of eye movement to the other are still poorly understood, even though they could bring a significant contribution to the understanding of how the CNS co...
متن کاملQuantitative analysis of catch-up saccades during sustained pursuit.
During visual tracking of a moving stimulus, primates orient their visual axis by combining two very different types of eye movements, smooth pursuit and saccades. The purpose of this paper was to investigate quantitatively the catch-up saccades occurring during sustained pursuit. We used a ramp-step-ramp paradigm to evoke catch-up saccades during sustained pursuit. In general, catch-up saccade...
متن کاملInhibition of steady-state smooth pursuit and catch-up saccades by abrupt visual and auditory onsets.
It is known that visual transients prolong saccadic latency and reduce saccadic frequency. The latter effect was attributed to subcortical structures because it occurred only 60-70 ms after stimulus onset. We examined the effects of large task-irrelevant transients on steady-state pursuit and the generation of catch-up saccades. Two screen-wide stripes of equal contrast (4, 20, or 100%) were br...
متن کاملHead impulses in complete bilateral vestibular loss: catch-up saccades require visual input.
Patients with bilateral vestibular loss (BVL) experience oscillopsia during passive head movements,(1) e.g., walking or driving. Because their vestibulo-ocular reflex does not stabilize gaze with compensatory eye movements, patients with vestibular deficiency make refixation saccades to a target.(2) Some can trigger directionally accurate ”covert” saccades during head movements and ”overt” sacc...
