Orientation deprivation in cat: what produces the abnormal cells?

When an animal is reared with goggles containing stripes of a single orientation, many cells in the visual cortex become abnormal. To find out whether these abnormal cells result from orientation deprivation per se or from other features of goggle rearing we reared kittens with goggles containing stripes of many orientations. The data suggest that orientation deprivation contributes to the development of abnormal cells but is not its sole cause.
