Document Summary

Kinesiology 1080b: topic #9 closed-loop motor control. Most aspects of vision are at the level of the retina (where photons are converted into bioelectrical signals) Most sophisticated pathway is from retina to lateral geniculate nucleus (lgn: lgn found in thalamus, vision is projected to v1. From v1 signals are sent to different areas depending on the situation: perceptual judgements v1 to inferotemporal cortex. V1 to inferotemporal cortex is called the ventral visual pathway: visual information aiding in making movements (reaching, etc. ) More basic pathway from retina to superior colliculus to pulvinar in thalamus which can directly project to posterior parietal cortex: reflexive movements, used in unexpected visual events, called the extra geniculate pathway. The human eye (1 or 2 definition questions on final exam) Cornea transparent part of the front of the eye; provides optical power by refracting light. Iris coloured part of the eye; controls light levels similar to a camera aperture.
