Document Summary

Eye movement for medial rectus muscle: towards the nose. Imagine an animal with a lesion n left v1 (right v1 is maintained). It would not saccade to stimuli in the right visual field. The animal now can saccade to targets in the blind field (sprog effect) Selective spatial attention: pay attention to different visual fields (focus on one part of your vision while ignoring the other) Attentional modulation is a critical part of perception. Voluntary eye movements: saccade, fixation (contolling eye movements to stay still) and smooth pursuit (effect tha toyu get when youre visually tracking a slowly moving object) Involunary eye movements: can"t control micro movements, vor (eye moves when head moves), optokinetic nystagmus. Preventing visual fading, accentuating sharp details, allowing to see behind eye blood vessels. Rolling down a hill on your side, spinning around on the spot. Fluid is weightless in zero gravity so there would be no vor.
