The mammalian vertebrate visual system has a partial division of labor. In general, the parvocellular system is specialized for perception of color and fine details. The magnocellular system is specialized for perception of depth, movement, and overall patterns. One system in the cerebral cortex is responsible for shape perception. Damage to specific areas beyond the primary visual cortex can impair specific aspects of vision, such as facial recognition, color constancy, and motion perception.
