You develop a local blindness, as though you had destroyed the corresponding part of your retina.
If you damage a certain part of your primary visual cortex, you develop a local blindness, as though you had destroyed the corresponding part of your retina. The visual world is thus systematically mapped onto the geniculate and cortex. What was not at all clear in the 1950s was what the mapping might mean. Simply stated, it is the area of the occipital lobe in the back of the brain responsible for processing visual information into an image that the person sees. The visual assoc … iation cortex is responsible for associating these images with items the person knows. The term cerebral cortex typically refers to all 4 lobes in the human brain (occipital, parietal, temporal, and frontal). It would be impossible to say what results from general cerebral cortex damage as the brain carries out so many different functions which are not evenly dispersed across the cortex. Research could lead to new rehabilitative therapies when visual cortex is damaged. It's a chilling thought--losing the sense of sight because of severe injury or damage to the brain's visual cortex. Answer by Llflasch. Confidence votes 8. You can become blind if the outercore is damaged because it is connected to your brain and your eyes. If you damage the visual association area of your brain, you can still see but you can't comprehend what you're looking at. Damage at site #2: partial damage to the left optic nerve. Here, information from the nasal visual field of the left eye (temporal part of the left retina) is lost. Damage at site #3: the optic chiasm would be damaged. In this case, the temporal (lateral) portions of the visual field would be lost. Damage at site #4 and #5: damage to the optic tract (#4) or the fiber tract from the lateral geniculate to the cortex (#5) can cause identical visual loss. In this case, loss of vision of the right side. Partial damage to these fiber tracts can cause other predictable visual problems.
