Critical periods: motion sensitivity is early in all areas.
Recent work shows that global motion sensitivity, a property of extrastriate cortex, can be altered by early visual deprivation, while binocularity, a property of primary visual cortex, is still plastic. This contradicts the hypothesis that critical periods end later at higher levels of the system.
