Document Summary

Up imagine an animal with a lesion in left v1 only. The animal now can saccade to targets in the blind field. Spatial attention: pay attention to different part of your vision field. In v4, there is an area highly associated to eye movement seems to be excited by attention. Interaction of eye movement control with vision is highly complex. Eye movement control appears inter-linked with visual spatial attention (cid:1) (cid:1) Voluntary eye movements: saccade, fixation, smooth pursuit. Microsaccades, drifts, tremors (fixation eye movements: vor (vestibule-ocular reflex, optokinetic nystagmus (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) By allowing to see behind eye blood vessels micro movement. Very small, require high precision instruments to measure. Contribute to : preventing visual fading, allowing us to see behind the blood vessels of the eye, improve visibility of sharp details. What are effective ways of inducing vestibular nystagmus (requires (cid:1) (cid:1) continuous vor)? (cid:1) (cid:1) (cid:1) Rolling down a hill on your side.
