Document Summary

Individuals missing one type of opponent system (lack of photo-pigment) In the visual cortex respond maximally to very specific information (e. g. only vertical lines or only diagonal lines) Parallel processing many systems simultaneously analyzing and integrating information. Kittens rose with only vertical lines (or only horizontal lines) for 5hr/day. 5 months of age 5 hr. /day of normal environment and the rest of the time in darkness. If raised in vertical striped environment: would only track vertical lines (not horizontal) Feature detectors in the brain did not fire to vertical lines. In human born with cataracts who were deprived of normal visual stimuli. If cataract were removed prior to age 1- good vision. If not removed by age 10, many problems with visual acuity . *individuals born blind who had their vision restored in adulthood did not recover vision for form or detail without touching the object. *but brain unable to make sense of the visual chaos .
