Brain and vision. Artwork of a man's head, brain and eyes seen from above, with arrows (white) showing the 'two streams' hypothesis of visual processing. Sensory input from the left eye travels along the optic nerve to the rear and opposite side of the brain (with the reverse happening for the other eye). The 'two streams' hypothesis states that after the information reaches the visual cortex (pink) in the occipital lobe, there are two paths it can follow. One is the dorsal stream (the 'where' pathway) to the parietal lobe (green). The other is the ventral stream (the 'what' pathway) along the temporal lobe (purple).
