o Each eye respond to light on both sides of the visual field (side of the head its on and the opposite) o Nasoretina receives from the ipsolateral visual field o Temporal retina comes from contralateral o Each optic nerve carries info about the ipsolateral and contralateral, at the chiasm axons carrying ipso info cross over to the opp hemisphere o While each retina receives infor from both fields, each hemisphere of brain is only receiving info from the contra lateral visual field o Image projected on retina is up side down and reversed and maintained all the way back to the cortex Visual field deficits – see slide o Cut the right optic nerve you terminate info coming from right visual field – no stereoscopic vision o Cut the optic chiasm – loss of both temporal visual field o Cut some of the axons from both eyes – lose left side of space from both eyes o Cut lower part of the optic radiation – superior temporal left side of space Parvocellular and Magnocellular streams: anatomical and physiological differences
