Even at the very early stage of the retina, an important division arises between two parallel visual streams, the dorsal stream and the ventral stream. The dorsal stream projects to the parietal cortex, and is responsible for movements in relation to objects, many of them of a routine or reflex nature. It is also seen as an answer to the ‘where is it?’ location question. The processing of the dorsal is unconscious, and is faster than the consciousness-related processing of the ventral stream. Speed is adaptive for the dorsal because it has to respond to immediate developments in the external environment. Damage to the dorsal stream is shown to lead to deficits in movements and actions, rather than problems with visual perceptions. On the other hand, damage to the ventral stream results in difficulties in recognising…
