Document Summary

Cerebral cortex is effectively programmed at birth, this part to vision and visual processing and that part to hearing, that to touch, and so on. John hull, a professor who had developed cataracts at 13 yrs, became completely blind in his left eye four years later, right eye remained reasonable until he was 35 then started to deteriorate. Lost the visual images and memories and the very idea of seeing, concepts like here and there and facing seemed to lose meaning for him and even the sense of objects having appearances visible characteristics vanished. Could not imagine how the numeral 3 looked, could construct a motor image of a 3 but not a visual one. Two years after being completely blind hull had become so nonvisual, resembled someone who had been blind since birth. Cortical blindness that can happen if the primary visual cortex is damaged.
