The mosts probable reason that both cats and humans have difficulty wtih recognition of objects if deprived of visual stimuli during the critical period is that:
a) neurons in the primary visual cortex die.
b) their cortical cells lack the sharply tuned receptive fields that make recognition possible.
c) they can't perceive color
d) the rods and cones no longer work
